Background/Objectives: Patients with advanced ovarian cancer face a high risk of venous thromboembolism (VTE). This study evaluates the incidence and risk factors for pulmonary thromboembolism (PE) in patients with advanced high-grade serous ovarian carcinoma (HGSOC) undergoing primary treatment, with a focus on personalized risk stratification. Methods: A retrospective analysis was conducted on women with FIGO stage IIIA-IVB HGSOC treated at the University Hospital of Parma between January 2012 and May 2023. All patients underwent CT-based staging prior to primary treatment. When resectability was uncertain, diagnostic laparoscopy and the Fagotti score were performed. Based on cytoreductive potential, patients received either primary debulking surgery (PDS) followed by adjuvant chemotherapy (AC) or neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) and AC. The Khorana score, a thromboembolic risk model, was calculated prior to chemotherapy. Logistic regression was used to assess the association between baseline characteristics and PE. Results: Among 167 HGSOC patients analyzed, 13 (7.8%) experienced PE. Among the 115 patients undergoing diagnostic laparoscopy, each 2-point increase in the Fagotti score above 8 raised PE risk by 76% (OR 1.76, p = 0.006, 95% CI: 1.17–2.63). Patients undergoing NACT-IDS had a significantly higher risk of PE (OR 4.04, 95% CI: 1.19–13.74, p = 0.02) than patients who underwent PDS. A Khorana score of 3 was an independent predictor of PE (OR 37.66, 95% CI: 2.43–582.36, p = 0.009). Conclusions: Based on our results, NACT followed by IDS or a Fagotti score greater than 8 were associated with increased PE risk in HGSOC patients. Khorana score was the strongest predictor of PE in HGSOC patients. Full article

Background: Lymphomas account for approximately 10% of cancers diagnosed during pregnancy, with Hodgkin’s lymphoma being the most common. However, non-Hodgkin lymphomas, including primary mediastinal large B-cell lymphoma (PMBCL), also represent a significant proportion. Both mediastinal lymphomas and pregnancy develop a hypercoagulable state, increasing the risk of venous thromboembolism and massive pulmonary embolism (PE), requiring extracorporeal membrane oxygenation (ECMO). Methods: Clinical data, blood test and imagings have been collected by the medical records of the patient. Results: We present a 25-year-old woman, at 32 weeks of gestation, who presented to the emergency department with progressive dyspnea and asthenia. Echocardiography revealed a hemodynamically significant pericardial effusion and severe right ventricular dysfunction. Given the severity of her condition, she underwent an emergency caesarean section and subsequently a pericardial drainage. A chest computed tomography scan revealed an incidental mediastinal mass along with a massive PE. Despite pericardial drainage, she remained hemodynamically unstable. Since thrombolysis was contraindicated for the recent cesarean section, venoarterial ECMO was initiated. Systemic anticoagulation was guaranteed by heparin, which shifted to argatroban for heparin resistance. The mediastinal mass was also biopsied, and the diagnosis of PMBCL carried out. Cytoreductive chemotherapy was initiated with the COMP-R regimen (i.e., cyclophosphamide, vincristine, methotrexate, prednisone, and rituximab), and the patient progressively improved up to ICU and hospital discharge. Conclusions: This case highlights the challenges in managing a complicated patient requiring early multidisciplinary intervention, which was crucial for stabilizing the patient and optimizing fetal and maternal prognosis.

Pulmonary artery leiomyosarcoma is an extremely rare disease, with only a few dozen cases reported worldwide to date. This disease is easily misdiagnosed as pulmonary thromboembolism, leading to improper treatment and accurate diagnosis in the later stages of the disease. Furthermore, this delayed diagnosis may also be the reason for the extremely high mortality rate of patients suffering from it. Early invasive surgery with the goal of complete surgical resection is the standard treatment method. Chemotherapy and radiation therapy have been tried with variable outcomes. Full article

Cancer is associated with an increased risk of developing venous thromboembolism, due to its direct influence on the three pillars of Virchow’s triad (e.g., compression on the blood vessels by the tumour, blood vessels invasion, and cytokine release), together with the effect of exogenous factors (such as chemotherapy, radiotherapy, surgery). In cancer patients, the risk of thrombosis at unusual sites, such as splanchnic, ovarian and renal vein thrombosis, is also increased. Abdominal vein thromboses are frequently incidental findings on abdominal imaging performed as part of the diagnostic/staging workup or the follow-up care of malignancies. There is little evidence on the management of unusual site venous thromboembolism in cancer patients since there are only a few specific recommendations; thus, the management follows the general principles of the treatment of cancer-associated deep vein thrombosis and pulmonary embolism. This narrative review summarises the latest evidence on cancer-associated abdominal vein thrombosis, i.e., thrombosis of the splanchnic, ovarian and renal veins. Full article

Purpose: Previous studies have indicated that patients with muscle-invasive bladder cancer with non-O blood types have an increased risk of experiencing thromboembolic events (TEEs). This is finding is in relation to neoadjuvant-chemotherapy (NAC)-naïve patients. Aim: to establish the risk of TEEs and any association with blood types among NAC patients as well as NAC-naïve patients. Methods: Cystectomized patients at four centres treated from 2009 to 2018 (n = 244) were analysed. The quantities of patients corresponding to each blood group were as follows: A—108 (44%); O—99 (41%); B—30 (12%); and AB—7 (3%). NAC patients (n = 167) and NAC-naïve NAC-eligible patients (n = 77) were assessed. In total, 54 women (22%) and 190 men (78%), with a median age of 69 years, were included in the study. The occurrence of any type of TEE from six months pre-cystectomy to 12–24 months after was analysed using logistic regression adjusted for NAC and confounders. Results: Sixty-six TEEs were detected in 21% of the patients (n = 52). Pulmonary embolus (n = 33) and deep venous thrombosis (n = 11) were the most common forms. No significant differences between blood types were found in the analysis, although B blood type had a nearly significant increased crude risk compared with O blood type, for which there was an OR of 2.48 (95% CI 0.98–6.36). Adjustment for NAC and covariates weakened the OR, which plummeted to 1.98 (95% CI 0.71–5.51). Conclusions: No significant associations were found between blood types and TEE occurrences in this cohort including both NAC and NAC-naïve NAC-eligible patients. Full article

Orthopedic surgery and soft-tissue sarcoma (STS) both independently increase the risk of developing symptomatic venous thromboembolic events (SVTE), but there are no established risk factors or guidelines for how to prophylactically treat patients with STS undergoing surgery. The objectives of this study were to (1) identify the prevalence of SVTE in patients undergoing STS surgery, (2) identify risk factors for SVTE, and (3) determine the risk of wound complications associated with VTE prophylaxis. This retrospective study was conducted in a tertiary level, academic hospital. A total of 642 patients were treated for soft-tissue sarcoma in the lower extremity with follow up for at least 90 days for the development of SVTE such as deep venous thrombosis and pulmonary embolism. Multivariate logistic regression was used to identify predictors for these events by controlling for patient characteristics, surgical characteristics, and treatment variables, with significance held at p < 0.05. Twenty eight patients (4.36%) were diagnosed with SVTE. Multivariate analysis found six significant predictors ordered based on standardized coefficients: pre-operative (PTT) partial thromboplastin time (p < 0.001), post-operative PTT (p = 0.010), post-op chemotherapy (p = 0.013), metastasis at diagnosis (p = 0.025), additional surgery for metastasis or local recurrence (p = 0.004), and tumor size larger than 10 cm (p < 0.001). The risk of wound complications (p = 0.04) and infection (p = 0.017) increased significantly in patients who received chemical prophylaxis. Our study identifies risk factors for patients at increased risk of developing VTE. Further prospective research is necessary to identify which protocols would be beneficial in preventing SVTE in high-risk patients with a low profile of wound complications. Full article

Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal disease that obstructs pulmonary vessels, leading to pulmonary hypertension (PH) and right-sided heart failure causing rapid progressive dyspnea in patients with cancer. This retrospective chart review involved nine patients with PTTM who were first clinically diagnosed in a tertiary emergency department (ED) between January 2015 and June 2021. They underwent laboratory tests, chest radiography, chest computed tomography (CT), and echocardiography. All patients presented with severe and rapidly progressive dyspnea within a few days, a high oxygen demand. The right ventricle (RV): left ventricle ratio was >1 on chest CT, and no life-threatening pulmonary thromboembolism (PTE) was observed. Echocardiographic findings indicated that all patients had moderate-to-severe RV dilatation with a D-shaped LV. The median tricuspid regurgitation maximum velocity was 3.8 m/s, and the median RV systolic pressure was 63 mmHg, indicating severe PH. The median value of tricuspid annular plane systolic excursion was 15 mm, showing a decrease in RV systolic function, and McConnell’s sign was observed in five patients. Two patients immediately underwent chemotherapy and are currently alive. PTTM should be suspected and evaluated using echocardiography in patients with cancer presenting to the ED with acute dyspnea and RV failure without PTE. Full article

The primary objective of this open-label, two chemotherapy arm, phase 4 study was to evaluate the safety and efficacy of newly developed recombinant granulocyte colony-stimulating factor (rG-CSF) used to prevent neutropenia-related complications in patients with metastatic breast cancer treated with docetaxel (75 mg/m2) and doxorubicin (50 mg/m2) or docetaxel (100 mg/m2) alone. Material and Methods. A total of 50 patients who were treated with a maximum of 6 cycles of either docetaxel-doxorubicin (36 patients) or docetaxel alone (14 patients) every 21 days were recruited from 3 centers in Lithuania. All the patients received study medication rG-CSF at a dosage of 5 μg/kg per day (Sicor Biotech UAB, Teva Group) from day 2 of each cycle and continued for minimum 5 days or until absolute neutrophil count reached ≥1.5×109/L. Results. A total of 611 adverse events were reported. Most of them were related to myelotoxic chemotherapy. Two patients withdrew due to adverse events (neuropathy and bone pain). One patient died possibly because of pulmonary thromboembolism. The most frequently reported adverse events related to study drug in the docetaxel-doxorubicin and docetaxel groups were leukocytosis (22% and 21%, respectively), bone pain (19% and 21%, respectively), and headache (8% and 14%, respectively). The incidence of grade 4 neutropenia in both the groups was 47% and 29%, respectively, in all cycles and 42% and 21%, respectively, in cycle 1. The incidence of febrile neutropenia was 8% in cycle 1 and 14% across all cycles. The mean duration of febrile neutropenia was 2.1 days (SD, 1.9) in cycle 1 and 2.14 days (SD 2.0) across all cycles in both the treatment groups. Conclusion. This study provide data that the study drug rG-CSF has the expected safety and could be an efficacious medication to decrease the risk of febrile neutropenia and related complications of myelosuppressive chemotherapy in patients with metastatic breast cancer.
