Objective: To analyze clinical prognostic factors for survival after recurrence of high-grade, advanced-stage ovarian-peritoneal-tubal carcinoma and to develop a nomogram to predict individual survival after recurrence.
Methods: We retrospectively analyzed patients treated in multicenter Gynecologic Oncology Group protocols for stage III and IV ovarian-peritoneal-tubal carcinoma who underwent primary debulking surgery, received chemotherapy with paclitaxel and a platinum compound, and subsequently developed recurrence. Prognostic factors affecting survival were identified and used to develop a nomogram, which was both internally and externally validated.
Results: There were 4,739 patients included in this analysis, of whom, 84% had stage III and 16% had stage IV ovarian carcinoma. At a median follow-up of 88.8 months (95% CI 86.2-92.0 months), the vast majority of patients (89.4%) had died. The median survival after recurrence was 21.4 months (95% CI 20.5-21.9 months). Time to recurrence after initial chemotherapy, clear cell or mucinous histology, performance status, stage IV disease, and age were significant variables used to develop a nomogram for survival after recurrence, which had a concordance index of 0.67. The time to recurrence alone accounted for 85% of the prognostic information. Similar results were found for patients who underwent second look laparotomy and had a complete pathologic response or received intraperitoneal chemotherapy.
Conclusion: For individuals with advanced-stage ovarian carcinoma who recur after standard first-line therapy, estimated survivals after recurrence are closely related to the time to recurrence after chemotherapy and prognostic variables can be used to predict subsequent survival.

Background: De-intensification of anti-cancer therapy without significantly affecting outcomes is an important goal. Omission of axillary surgery or breast radiation is considered a reasonable option in elderly patients with early-stage breast cancer and good prognostic factors. Data on avoidance of both axillary surgery and radiation therapy (RT) is scarce and inconclusive.

Background And Aims: Self-expandable metal stents (SEMS) are effective in alleviating malignant colorectal obstruction. However, bowel perforation following SEMS placement remains a significant concern, as it can adversely affect oncological outcomes. This study aimed to evaluate the recurrence and overall survival rates associated with SEMS-related bowel perforations.

Cervical cancer is preventable with screening and vaccination approaches; however, access to these preventative measures is limited both nationally and globally and thus many women will still develop cervical cancer. Novel treatments and practice-changing research have improved cervical cancer outcomes over the past few decades. In this Review, we discuss clinical trials that have refined or redefined the treatment of cervical cancers across the early stage, locally advanced, persistent, recurrent and/or metastatic disease settings.

Multiple myeloma (MM) is a haematological lymphoid malignancy marked by significant morbidity due to severe complications. Despite advances in targeted therapies, including proteasome inhibitors and the BCL-2 inhibitor venetoclax, drug resistance frequently occurs, with the underlying mechanisms poorly understood. This study investigates the role of lysosome-associated protein transmembrane 5 (LAPTM5) in conferring resistance to venetoclax in relapsed MM.

Background: Thymic epithelial tumors (TETs), including thymoma and thymic carcinoma, are rare thoracic tumors of the anterior mediastinum. For those with advanced disease, platinum-based chemotherapy is used as first-line treatment. However, there is no standard regimen established for TET at progression after initial therapy, and treatment options for advanced/recurrent TETs are limited.
