Most patients with non-small-cell lung cancer (NSCLC) present with advanced/metastatic disease at diagnosis, and molecular profiling is critical in guiding treatment decisions. This retrospective cohort study aimed to characterize EGFR mutations (EGFRm) in advanced/metastatic NSCLC patients, treatment patterns, and real-world outcomes. Adults diagnosed between 2018 and 2021 and treated at a Comprehensive Care Center were included. Time-to-event outcomes were analyzed using the Kaplan–Meier method. A total of 110 patients were included, with a median age of 69.0 years (range, 37–93), 76.4% female, and 83.2% non-smokers. About 97.3% had adenocarcinomas, with 93.6% at stage IV, 40.9% with ≥ three metastatic sites (brain metastases in 24.5%), 33.6% ECOG 2–4, and 58.2% with an EGFR exon-19 deletion. A minority started supportive care or curative-intent treatment, and 81.8% underwent first-line palliative systemic therapy (TKIs, 91.1%; chemotherapy, 8.9%). Median real-world overall survival (rwOS) was 18.9 months (95% CI, 13.8–28.1). Worse rwOS was observed in patients with ECOG 2–4 versus ECOG 0–1 (10.3 vs. 22.8 months; HR 1.82, 95% CI 1.17–2.85; p = 0.008) and in patients with exon-21 L858R versus exon 19 deletions (15.8 vs. 24.2 months; HR 1.59, 95% CI 1.00–2.54; p = 0.048). In patients treated with palliative systemic treatment, median progression-free survival was 10.9 months (95% CI, 8.8–13.6). This study provides important insights regarding real-world characteristics, treatment patterns, and outcomes from a cohort of EGFRm advanced/metastatic NSCLC patients. Full article

Background/Objectives: Colorectal cancer (CRC) is one of the major epidemiological oncological confronts with established risk factors, including male sex. Still, CRC is reported among the leading malignancies in the female population. The necessity for possible, easily accessible prognostic factors is required to improve patient outcomes. This study aimed to assess sex-related differences in nine-month four-stage CRC results of palliative systemic therapy. Methods: A total of 67 patients (39 males) with a median age of 70 (64–76) years were referred for first-line palliative chemotherapy due to end-stage colorectal cancer diagnosis. The CRC advancement was evaluated by computed tomography (CT) before and 9 months after chemotherapy. The demographical and clinical characteristics were evaluated for nine-month therapy outcomes, including mortality risk and CT scan results. Results: The nine-month mortality risk in female and male groups was indifferent, reaching 21% (6 patients) and 21% (8 patients), respectively (p = 0.935). Among survivors, therapy response was observed in 6 (21%) female and 20 (51%) male patients (p = 0.056). In multivariable analysis, the male sex (OR: 3.91, 95% CI: 1.09–14.05, p = 0.037) and RDW (OR: 0.61, 95% CI: 0.42–0.88, p = 0.008) were found to be significant for disease response to systemic therapy based on CT scan results. The ROC curve for predictive role yields a sensitivity of 71.1%, specificity of 57.8%, and an area under the curve (AUC) of 0.726. Conclusions: Our analysis points out the possible favorable role of the male sex on nine-month systemic therapy response in palliative CRC. The RDW-CV can be regarded as a possible indicator of chemotherapy response in colorectal cancer. The mortality risk within 9 months of systemic therapy is comparable between males and females.

Pancreatic cancer is an aggressive malignancy, with a current 5-year survival rate in the United States of approximately 13.3%. Although the current standard for resectable pancreatic cancer most commonly includes neoadjuvant chemotherapy prior to a curative resection, surgery, in the majority of patients, has historically been palliative. The latter interventions include open or laparoscopic bypass of the bile duct or stomach in cases of obstructive jaundice or gastric outlet obstruction, respectively. Non-surgical interventional therapies started with percutaneous transhepatic biliary drainage (PTBD), both as a palliative maneuver in unresectable patients with obstructive jaundice and to improve liver function in patients whose surgery was delayed. Likewise, interventional radiologic techniques included the placement of plastic and ultimately self-expandable metal stents (SEMSs) through PTBD tracts in patients with unresectable cancer as well as percutaneous cholecystostomy in patients who developed cholecystitis in the context of malignant obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) and stent placement (plastic/SEMS) were subsequently used both preoperatively and palliatively, and this was followed by, or undertaken in conjunction with, endoscopic gastro-duodenal SEMS placement for gastric outlet obstruction. Although endoscopic ultrasound (EUS) was initially used to cytologically diagnose and stage pancreatic cancer, early palliation included celiac block or ablation for intractable pain. However, it took the development of lumen-apposing metal stents (LAMSs) to facilitate a myriad of palliative procedures: cholecystoduodenal, choledochoduodenal, gastrohepatic, and gastroenteric anastomoses for cholecystitis, obstructive jaundice, and gastric outlet obstruction, respectively. In this review, we outline these procedures, which have variably supplanted surgery for the palliation of pancreatic cancer in this rapidly evolving field. Full article

Stereotactic Body Radiotherapy (SBRT) has emerged as a pivotal treatment modality for early-stage non-small cell lung cancer (NSCLC), offering highly precise, high-dose radiation delivery. However, several clinical challenges remain, particularly in the treatment of central or ultracentral tumors, which are located near critical structures such as the heart, bronchi, and great vessels. The introduction of MRI-guided SBRT has significantly improved targeting precision, allowing for better assessment of tumor motion and adjacent organ structures. Additionally, SBRT has demonstrated efficacy in multifocal NSCLC, providing an effective option for patients with multiple primary tumors. Recent advances also highlight the role of SBRT in locally advanced NSCLC, where it is increasingly used as a complementary approach to concurrent chemotherapy or in cases where surgery is not feasible. Moreover, the combination of SBRT with immunotherapy has shown promising potential, enhancing tumor control and immunological responses. Furthermore, SBRTs application in SCLC is gaining momentum as a palliative and potentially curative option for selected patients. This narrative review explores these evolving clinical scenarios, the technical innovations supporting SBRT, and the integration of immunotherapy, providing an in-depth look at the new frontiers of SBRT in lung cancer treatment. Despite the challenges, the ongoing development of personalized approaches and technological advancements continues to push the boundaries of SBRTs clinical utility in lung cancer. Full article

Pleural malignancies represent a clinically devastating group of oncological disorders, most commonly arising from metastatic disease, with lung and breast cancers being the most frequent primary sites. Malignant pleural mesothelioma is a primary malignancy of the pleura and occurs less often than metastatic pleural disease. Pleural malignancies often present with malignant pleural effusion, which typically indicates advanced-stage disease and is associated with poor overall prognosis. Treatment of pleural malignancies includes both palliative and definitive approaches. Palliative interventions primarily aim to relieve symptoms and improve quality of life. Definitive treatments include systemic chemotherapy, targeted therapy, and immunotherapy, depending on the type and molecular profile of the underlying tumor. In mesothelioma, platinum-based chemotherapy in combination with pemetrexed remains the cornerstone of treatment, while the combination of nivolumab and ipilimumab is recommended as first-line therapy for unresectable disease. For metastatic disease, systemic therapy is typically tailored to the primary tumor’s characteristics. Intrapleural administration of chemotherapeutic agents is one of the therapeutic strategies and hyperthermic intrathoracic chemotherapy and pressurized intrathoracic aerosol chemotherapy are the most recent innovations that are under active investigation. This review provides an up-to-date synthesis of systemic chemotherapy strategies for pleural malignancies, their integration with targeted and immune-based therapies, and recent advances in intrapleural chemotherapy modalities. It also explores existing knowledge gaps and outlines directions for future research and potential changes in clinical practice. Full article

Background: Colorectal liver metastases (CRLM) occur in up to 50% of colorectal cancer with a significant impact on patient survival, of whom only 20–30% will be considered suitable for surgical treatment. Despite the progress in systemic therapies, palliative chemotherapy alone results in a 5-year overall survival (OS) < 10%. Recently, liver transplantation (LT) has been reconsidered as an option and demonstrates improved survival in highly selected patients. This study assessed the impact of implementing a standardised patient selection protocol (LITORALE) on post-transplant outcomes for unresectable CRLM (uCRLM) at a high-volume single centre. Methods: This is a prospective observational study including all consecutive patients transplanted for uCRLM at our institution between July 2015 and September 2024. This prospective observational study evaluated the impact of the LITORALE protocol on post-transplant outcomes in uCRLM patients at a single centre. Patients who underwent LT between July 2015 and September 2024 were grouped into pre-LITORALE (2015–2021) and LITORALE (post-2021) cohorts. Recipient profiles, transplant variables, and post-transplant outcomes were compared. Results: Twenty-one patients were included (eight pre-LITORALE, thirteen LITORALE). The LITORALE group had a lower median number of lesions (4 vs. 17.5, p = 0.004), a smaller major lesion size (3 cm vs. 5.5 cm, p = 0.082), and a significantly lower tumour burden score (6.32 vs. 18.02, p = 0.002). Similar to recent major clinical trials, one- and three-years OS were 100% and 83%, respectively, after protocol introduction; recurrence patterns were significantly different, with reduced multi-site recurrences (7.7% vs. 50%, p = 0.048) and a higher incidence of lung-only recurrences in the LITORALE group (50% vs. 0%, p = 0.033). Conclusions: The introduction of the LITORALE protocol significantly influenced patient selection and recurrence patterns in LT for uCRLM. Although the limited number of patients and the short study timespan highlight the need for future validation, these preliminary results support the adoption of structured, multidisciplinary criteria to optimise oncologic outcomes.

Background: PIPAC is an innovative treatment that delivers low-dose aerosolized chemotherapy into the abdominal cavity of patients with peritoneal surface malignancies (PSMs). However, its role in the multimodal management of PSMs is unclear. Methods: We retrospectively analyzed data from 64 patients who underwent PIPAC for PSMs of a primary or secondary origin between June 2020 and December 2024 (median age of 64 years). Primary tumor sites included gastric (42.2%), colorectal (23.4%), ovarian cancer (21.9%), and others (12.5%). The median PCI was 15 (IQR 9–25), with ascites present in 60.9% of cases and a positive cytology in 48.4%. Results: A total of 82 PIPAC sessions were performed in 64 patients. The mean operation time was 96 min. Severe adverse events, defined as the Common Terminology Criteria for Adverse Events (CTCAE) of a grade ≥ 2, occurred in four patients (6.2%). The median hospital stay was 3 days, and systemic chemotherapy was resumed within 14 days after the procedure in 27 patients. Among the entire cohort, 37.5% received bidirectional therapy and 62.5% received palliative treatment, with a lower peritoneal cancer index (PCI) in the bidirectional group (9.5 vs. 23). The median overall survival (OS) was 32 months from diagnosis. Sixteen patients (25%) underwent two or more PIPAC sessions and showed an advantage in survival compared to patients who underwent only one procedure (3-year OS: 63.2% vs. 38.4%, p 0.030). Conversion surgery was achieved in 34.4%. Patients treated with a bidirectional intent demonstrated a longer OS (3-year: 66.0% vs. 33.9%, p 0.011). Colorectal and ovarian tumors exhibited better long-term outcomes compared to gastric cancer. Conclusions: PIPAC is a promising treatment for PSMs, with a low morbidity rate. Its favorable safety and short interval to systemic therapy resumption support its use as part of a bidirectional strategy. Full article

In this article, we present a case of a 49-year-old woman presenting with a recurrent metastatic neuroendocrine tumor. Background: Insulinomas are neuroendocrine tumors derived from beta cells of the pancreas that secrete insulin. Usually, they are benign tumors; however, metastatic insulinomas are an extremely rare malignant form of these tumors, carrying a significantly worse prognosis. Case Presentation: A 49-year-old woman, a patient in the University Hospital in Wroclaw in the Department of Endocrinology, Diabetes and Isotope Therapy, first presented with abdominal pain in 2009, when ultrasound and further examination led to the diagnosis of a tumor in the pancreas (a solid pseudopapillary tumor of the pancreas—meta NET G2), and the patient underwent distal pancreatectomy with splenectomy. For ten years, she was under observation, and her symptoms, such as abdominal pain, nausea, weight loss, and general weakness, reappeared in 2019. Then, magnetic resonance imaging (MRI) showed a lesion in the liver, and further histopathology revealed neuroendocrine tumor (NET) metastasis to the liver. In 2022, the patient presented with loss of consciousness and convulsion, loss of weight, and hypoglycemia after meals. In April 2022, the daily glycemic profile was recorded and a 72 h fasting test was performed; however, their results excluded insulinoma. Positron emission tomography–computed tomography (PET-CT) with 18F-fluorodeoxyglucose (18F-FDG) and PET with gallium-68-DOTA-(Tyr3)-octreotate (68Ga-DOTA-TATE) showed a metastatic proliferative process in the liver. Persistent hypoglycemia led to another hospitalization in May 2022, and repeated tests allowed for the diagnosis of insulinoma. Treatment with somatostatin analogs and diazoxide was started. A CT scan in November 2022 and a PET scan in January 2023 showed new metastases to the liver, bones, and cervical lymph nodes, and it was decided to intensify the treatment. In May 2023, the patient was qualified for Lutathera treatment for insulinoma at the University Clinical Hospital in Poznań. In June 2023, another disturbing symptom was reported by the patient, a painful lump in the breast. During diagnostics, metastases with high proliferation markers were found in both breasts. Two months later, in August 2023, the patient received another dose of Lutathera. In October 2023, significant progression of liver lesions, metastases to bones of the spine, ribs, and pelvis, and periaortic and pelvic lymphadenopathy were found as well as elevated values of neuron-specific enolase and calcitonin. The patient was also referred to the Palliative Medicine Home Hospice. In consultation with the Lower Silesian Cancer Center, the decision was made to forgo further treatment with PRRT and initiate systemic chemotherapy. Despite the chosen treatment, the patient died on 27/DEC/2023. Conclusions: This case report can serve clinicians, as it presents a case of an extremely rare and insidious tumor, metastatic insulinoma. Full article

The applicability of RHT in the treatment and supportive care of tumors has been discussed for years in many publications. There are hundreds of articles that have reported on the good acceptance and feasibility of HT, as well as its value in terms of controlling malignant diseases, enhancing response and, in some randomized controlled trials (RCTs), clear improvements in OS. Despite this, HT has never fully been accepted as a standard treatment among radiation and medical oncologists. The increased activity that HT offers in the context of chemotherapy (CHT), radiotherapy (RT), chemoradiotherapy (CRT), and immunotherapy, thus facilitating programmed cell death (PCD), has been documented in many studies. This aspect has been demonstrated in many tumors, including soft tissue sarcoma, cancers of the cervix, esophagus, stomach, colon/rectum, pancreas, breast, head and neck, and prostate, and bone metastases. HT improves cancer cell death through many modalities, targeting both the tumor microenvironment (TME) and the cancer cells directly. Targeted HT increases the temperature of the primary tumor and surrounding tissues to 39–43 °C, causing the tumor cells to become more immune-responsive. HT can also activate the immune response of the TME through inducing heat shock proteins (HSPs), which also promote an immunological response and PCD. HT can oxygenate hypoxic tumors, facilitating RT-induced DNA damage in cancer cells. At present, it seems that the combination of HT and RT, CHT, and immunotherapy might lead to immune enhancement effects in the TME, making cancer cells more responsive to immunotherapies. This narrative review presents the novel aspects of HT reported in recent years. Full article

Pressurized intra-thoracic aerosol chemotherapy (PITAC) is a novel and promising strategy for the treatment of malignant pleural effusion (MPE). PITAC enables effective pleurodesis while potentially exerting an antineoplastic effect by delivering chemotherapeutic agents as a therapeutic aerosol into the thoracic cavity via a nebulizer. Our preliminary study involved nine patients with unresectable pleural mesothelioma (PM) treated with PITAC. Among them, one case was particularly emblematic for demonstrating notable oncological improvements in addition to well-known palliative benefits. This patient underwent two PITAC procedures, one year apart, without perioperative complications. Redo pleural biopsies from both previous and new sites revealed only fibrous tissue and inflammatory cells, with no evidence of malignancy. Beyond achieving pleurodesis, PITAC—by combining cytotoxic and sclerosing effects—may offer effective local antineoplastic control and represent a promising avenue for enhancing loco-regional therapy in PM.

Background: About 15–20% of breast cancers are HER2 positive. Approximately 15–24% of individuals with localized HER2-positive cancer develop metastatic disease after curative treatment, while 3–10% present with de novo metastasis. Survival has significantly improved with various anti-HER2 agents, but there is considerable heterogeneity at the individual level. Our study aims to identify factors influencing survival in de novo metastatic HER2-positive breast cancer using a large sample from the National Cancer Database (NCDB). Methods: Women with metastatic HER2-positive breast cancer diagnosed from 2010 to 2020 in the NCDB were included. Demographic, clinicopathological, treatment data, and overall survival (OS) were collected. Kaplan–Meier curves estimated OS. The log-rank test identified OS differences between groups in univariate analysis. The Cox proportional hazard model with backward elimination identified factors affecting OS in multivariate analysis. The 12-month, 36-month, and 60-month survival estimates, 95% confidence intervals (CIs), and adjusted hazard ratios were reported. Results: Among 5376 women with metastatic HER2-positive breast cancer from 2010 to 2020, the median OS was 55.95 months (95% CI 53.55-NE). Multivariate analysis identified age, Charlson–Deyo comorbidity score, histology, HER2 IHC expression, hormone receptor status, the number of metastatic sites, metastasis location, first-line chemotherapy, anti-HER2 therapy, hormone-blocking therapy, surgery at primary/non-primary sites, and palliative treatment as significant factors affecting OS. Race and radiation receipt were not significant. Conclusions: This is the largest analysis of overall survival estimates in de novo metastatic HER2-positive breast cancer to date in the real-world setting. We identified several independent prognostic factors influencing OS in this population. These findings will help individualize prognostication at diagnosis, optimize treatment strategies, and facilitate patient stratification in future trials. Full article

Background: Pancreatic ductal adenocarcinoma (PDAC) exhibits variable survival outcomes based on tumor location, with pancreatic head cancer (PHC) and pancreatic body/tail cancer (PBTC) differing in prognosis and treatment response. This study investigates the correlation between tumor location and survival outcomes in PDAC patients treated with standard chemotherapy regimens. Methods: A retrospective analysis of 604 PDAC patients (400 PHC, 204 PBTC) diagnosed between January 2015 and May 2024 at Houston Methodist Neal Cancer Center was conducted. Patients received either mFOLFIRINOX or gemcitabine/nab-paclitaxel as first-line therapy. Clinical data, including demographics, tumor stage, treatment modalities, and molecular profiles, were extracted from electronic records. Overall survival (OS) and progression-free survival (PFS) were assessed using Kaplan–Meier analyses and Cox proportional hazards models. Latent class analysis (LCA) identified patient subgroups based on shared clinical, demographic, and survival characteristics. Results: PHC patients demonstrated superior median OS (12 months) compared to PBTC (9 months, p = 0.012) and PFS (8 months vs. 5 months, p = 0.0008). Across both subtypes, mFOLFIRINOX was associated with significantly longer OS than gem/nab-paclitaxel (PHC: 18.8 vs. 12.7 months, p < 0.0001; PBTC: 14 vs. 6 months, p = 0.011). LCA revealed distinct clusters: in PHC, a curative-intent class (median OS > 24 months) contrasted with a palliative class (<6 months); in PBTC, an aggressive treatment class (median OS > 18 months) differed from a limited treatment class (<6 months). Cluster differences were linked to treatment intensity, stage, and radiation use. Conclusions: PHC is associated with better survival outcomes than PBTC, with mFOLFIRINOX outperforming gem/nab-paclitaxel in both subtypes. LCA highlights heterogeneous patient subgroups, suggesting opportunities for personalized treatment strategies in PDAC management. Full article

Interstitial lung disease (ILD) prevalence and survival are increasing due to improvement in scientific research together with clinical complications typical of advanced disease. Lung cancer (LC) is described as a possible event occurring in lung parenchyma in the context of fibrotic abnormalities that worsen patients’ prognosis. This growth of malignant cells on a fibrotic background has also been called scar-cinoma. For this reason, not only an early diagnosis but also personalized decisions on the best treatment approach should be considered for each patient in a multidisciplinary discussion, since in some cases chemotherapy or surgery could be detrimental for patients with pulmonary fibrosis. LC and lung fibrosis may share common pathogenetic mechanisms like an altered healing process in response to repeated tissue damage from environmental exposure in genetically susceptible individuals. Smoking history and air pollution together with mutations in telomere and surfactant protein genes lead to the production of cytokines and nitro derivatives in the microenvironment that facilitate the carcinomatous transformation during fibrogenesis. The evolution of LC therapy and the implementation of immunotherapy acting on targetable immune checkpoints have raised interest in evaluating ILD-LC actionable mutations. The main pathogenetic mechanisms, clinical presentations and treatment implications are presented in this review. Full article

Pleural carcinomatosis (PC) and malignant pleural effusion (MPE) affect up to 20% of patients with non-small cell lung cancer (NSCLC) and are usually synonymous with poor prognosis. Pressurized Intra-Thoracic Aerosol Chemotherapy (PITAC) is a novel and promising technique to control MPE in PC-NSCLC. This pilot study aimed to assess the feasibility, safety, and efficacy of PITAC in terms of palliative pleurodesis and evaluate the local antineoplastic control by analyzing patient-derived primary cell cultures. From January to December 2023, seven patients underwent PITAC with tailored doses of cisplatin and doxorubicin. There were four males and three females, with a median age of 65 (IQR:19) years. No operating room contamination by aerosolized chemotherapeutics was observed. No intraoperative complications occurred, and 30-day mortality was nil. One patient developed a postoperative prolonged air leak. The median chest tube stay was 2 (IQR:2) days, and the median hospital stay was 4 (IQR:2) days. No systemic toxicity nor hypersensitivity to chemotherapeutics were observed. All patients developed effective pleurodesis in 30 days. Cell cultures obtained from biopsy of PC-NSCLC sampled before PITAC formed confluent and monolayer sheets of attached tumor cells, while after 30 min from PITAC, cultures exhibited a significant reduction in the cancer cells’ growth. Effective pleurodesis was observed three and six months after surgery in all patients. PITAC is a safe and effective technique to control MPE recurrence and might revolutionize loco-regional therapy for PC-NSCLC. Further research should assess its oncological role. Full article

Radiation therapy is a medical treatment that uses high doses of radiation to kill or damage cancer cells. It works by damaging the DNA within the cancer cells, ultimately causing cell death. Radiotherapy can be used as a primary treatment, adjuvant treatment in combination with surgery or chemotherapy or palliative treatment to relieve symptoms in advanced cancer stages. Radiation therapy is constantly improving in order to enhance the effect on cancer cells and reduce the side effects on healthy tissues. Our results clearly demonstrate that proton therapy and, even more, carbon ion therapy appear as promising alternatives to overcome the radioresistance of various tumors thanks to less dependency on oxygen and a better ability to kill cancer stem cells. Interestingly, hadrons also retain the advantages of radiosensitization approaches. These data confirm the great ability of hadrons to spare healthy tissue near the tumor via various mechanisms (reduced lymphopenia, bystander effect, etc.). Technology and machine improvements such as image-guided radiotherapy or particle therapies can improve treatment quality and efficacy (dose deposition and biological effect) in tumors while increasingly sparing healthy tissues. Radiation biology can help to understand how cancer cells resist radiation (hypoxia, DNA repair mechanisms, stem cell status, cell cycle position, etc.), how normal tissues may display sensitivity to radiation and how radiation effects can be increased with either radiosensitizers or accelerated particles. All these research topics are under investigation within the ARCHADE research community in France. By focusing on these areas, radiotherapy can become more effective, targeted and safe, enhancing the overall treatment experience and outcomes for cancer patients. Our goal is to provide biological evidence of the therapeutic advantages of hadrontherapy, according to the tumor characteristics. This article aims to give an updated view of our research in radiation biology within the frame of the French “ARCHADE association” and new perspectives on research and treatment with the C400 multi-ions accelerator prototype.
