Article Synopsis
  • - Trastuzumab deruxtecan is a newly approved cancer treatment specifically for HER2-mutant non-small-cell lung cancer, and this study explored its effectiveness in treating other metastatic solid tumors with similar HER2 mutations.
  • - Conducted as an open-label, phase 2 study across 29 centers in multiple regions, it involved 102 patients aged 18 and older who had previously received treatment for their cancer and continued to experience disease progression.
  • - Results showed that the treatment led to a 29.4% objective response rate, indicating some level of effectiveness, and a median follow-up of nearly 9 months revealed information about its safety and anti-tumor activity.

Cervical cancer remains a leading cause of morbidity and mortality amongst females in Latin America (LATAM). Cervical cancer is a preventable disease and HPV vaccination is a main key strategy towards its elimination. This study analyzes HPV vaccine implementation current status and the main barriers to achieve adequate coverage in the region.

Background: Vulvar extramammary Paget disease is a rare chronic condition, that presents with non-specific symptoms such as pruritus and eczematous lesions. Because most of these lesions are noninvasive, the distinction between primary and secondary Paget disease is crucial to management.

Case Presentation: We report an unusual case of vulvar Paget disease associated with massive dermal vascular embolization, cervicovaginal involvement and metastasis to inguinal and retroperitoneal lymph nodes.

Purpose: Although chemoradiation therapy (CRT) with cisplatin remains the standard treatment of patients with locally advanced cervical cancer (LACC), 40% of patients present with disease recurrence. Additional treatment strategies are required to improve outcomes. We conducted a trial to evaluate the efficacy and safety of neoadjuvant chemotherapy (NAC) with cisplatin and gemcitabine followed by CRT.

Article Synopsis
  • The study looked at how keeping ovaries during surgery affects young women with early-stage low-grade endometrial cancer.
  • It analyzed data from women under 50 in the US and Japan who had surgery between 2000 and 2014.
  • The results showed that while more women in the US are keeping their ovaries, this option has different effects on cancer outcomes, with risks of recurrence or other cancers being higher in the Japan group.

Objectives: Enhanced Recovery After Surgery (ERAS) programs are mechanisms for achieving value-based improvements in surgery. This report provides a detailed analysis of the impact of an ERAS program on patient outcomes as well as quality and safety measures during implementation on a gynecologic oncology service at a major academic medical center.

Methods: A retrospective review of gynecologic oncology patients undergoing elective laparotomy during the implementation phase of an ERAS program (January 2016 through December 2016) was performed.

Background: Oxaliplatin-based chemotherapy can cause hepatic sinusoidal injury (HSI), portal hypertension, and splenic sequestration of platelets. Evidence suggests that bevacizumab may protect against HSI.

Methods: Two cohorts of metastatic colorectal cancer (CRC) were analyzed: a nonrandomized exploratory cohort of 184 patients treated at a single institution from 2003 to 2010 and a confirmatory cohort of 200 patients from a multi-institutional randomized trial (NO16966).

Objectives: Minimally invasive surgery (MIS) is a quality measure for endometrial cancer (EC) established by the Society of Gynecologic Oncology and the American College of Surgeons. Our study objective was to assess the proportion of EC cases performed by MIS at National Comprehensive Cancer Network (NCCN) centers and evaluate perioperative outcomes.

Methods: A retrospective cohort study of women who underwent surgical treatment for EC from 2013 to 2014 was conducted at four NCCN centers.

Background: Venous thromboembolic events (VTEs) are common and potentially fatal complications in cancer patients, and they are responsible for the second most common cause of death. Low molecular weight heparin (LMWH) is the gold-standard treatment, but the costs involved limit its use, especially in developing countries. Recently, the oral anticoagulant rivaroxaban, which directly inhibits factor Xa, was approved for VTE treatment.

It has been recognized for decades that angiogenesis is an important event in tumor growth and metastasis; the concept of the "angiogenic switch," whereby tumors acquire the ability to grow exponentially and disseminate beyond their primary site, is one of the central components in our understanding of cancer. A vast network of signaling molecules and receptors that are involved in the regulation of angiogenesis have been identified and characterized; most notably, the vascular endothelial growth factor (VEGF) family. Indeed, the VEGF family of growth factors and receptors has become a prototype for our understanding of angiogenesis during early development and in pathological conditions such as cancer.

Colorectal cancer is one of the most prevalent malignancies worldwide, and its incidence continues to rise. The treatment for advanced colorectal cancer has significantly evolved in the last decade, with the addition of a number of new therapeutic agents; however, 5-fluorouracil remains at the core of most therapeutic approaches for this disease. Novel therapies targeting specific pathways have been developed for this disease, and the vascular endothelial growth factor ligand and receptor have been of particular interest.
