Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country's fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypes─high-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.The NCCN Guidelines for Prostate Cancer address staging and risk assessment after a prostate cancer diagnosis and include management options for localized, regional, and metastatic disease. Recommendations for disease monitoring and treatment of recurrent disease are also included. The NCCN Prostate Cancer Panel meets annually to reevaluate and update their recommendations based on new clinical data and input from within NCCN Member Institutions and from external entities. This article summarizes the panel's discussions for the 2021 update of the guidelines with regard to systemic therapy for metastatic castration-resistant prostate cancer.

Durvalumab was approved by the FDA in February 2018 for patients with unresectable stage III NSCLC that has not progressed after platinum-based concurrent chemoradiotherapy (cCRT), and this regimen is the current standard of care. The objective of this study was to examine the cost-effectiveness of durvalumab following cCRT versus cCRT alone in patients with locally advanced, unresectable stage III NSCLC.

A 3-state semi-Markov model was used. Modeling was performed in a US healthcare setting from Medicare and commercial payer perspectives over a 30-year time horizon. Clinical efficacy (progression-free and post progression survival) and utility inputs were based on PACIFIC study data (ClinicalTrials.gov identifier NCT02125461; data cutoff March 22, 2018). Overall survival extrapolation was validated using overall survival data from a later data cutoff (January 31, 2019). The main outcome was the incremental cost-effectiveness ratio (ICER) of durvalumab following cCRT versus cCRT alone, calculated as the dandard of care in patients with unresectable stage III NSCLC.

In a US healthcare setting, durvalumab was cost-effective compared with cCRT alone, further supporting the adoption of durvalumab following cCRT as the new standard of care in patients with unresectable stage III NSCLC.Lynch syndrome is a heritable cancer syndrome caused by a heterozygous germline mutation in DNA mismatch repair (MMR) genes. MMR-deficient (dMMR) tumors are particularly sensitive to immune checkpoint inhibitors, an effect attributed to the higher mutation rate in these cancers. However, approximately 15% to 30% of patients with dMMR cancers do not respond to immunotherapy. This report describes 3 patients with Lynch syndrome who each had 2 primary malignancies 1 with dMMR and a high tumor mutational burden (TMB), and 1 with dMMR but, unexpectedly, a low TMB. Two of these patients received immunotherapy for their TMB-low tumors but experienced no response. We have found that not all Lynch-associated dMMR tumors have a high TMB and propose that tumors with dMMR and TMB discordance may be resistant to immunotherapy. The possibility of dMMR/TMB discordance should be considered, particularly in less-typical Lynch cancers, in which TMB evaluation could guide the use of immune checkpoint inhibitors.

Translation of basic discoveries to clinical care for patients with cancer is a difficult process greatly enabled by physician-trained researchers. Three categories of physicians, with responsibilities spanning from laboratory and preclinical research to direct patient care, are involved in the translational research continuum physician-scientist (PS), clinician investigator (CI), and academic clinician (AC).

To define how protected time for research efforts is supported, the Association of American Cancer Institutes (AACI) conducted a survey of their member institutions, obtaining 56 responses documenting time spent in research and clinical activities across multiple cancer disciplines, and providing information about funding streams for the different categories of cancer physicians.

Responses showed that PSs and ACs are minimally involved in clinical research activities; the driver or clinical research in academic cancer centers is the CI. A significant concern was a lack of stable funding streams for nonbillable clinical research activities, putting the sustainability of the CI in jeopardy. Limited funding was derived from hospital sources, with most support derived from cancer center sources.

This study highlights the importance of the CI in translational cancer medicine and represents a call to action for institutions and research funding agencies to develop new programs targeted toward CI support to ensure continued progress against cancer.

The use of this surgical corridor has been pervasive throughout the 20th century. It has been utilized by multiple disciplines for both clinical and experimental purposes, although its historical origin is medically and ethically controversial. Hermann Knapp first introduced the orbital surgical technique in 1874, and Rudolf Krönlein introduced his procedure in 1889. Rivalry between Walter Dandy in neurosurgery and Raynold Berke in ophthalmology further influenced methods of tackling intracranial and intraorbital pathologies. In 1946, Walter Freeman revolutionized psychosurgery by completing seemingly successful transorbital leucotomies and promoting their minimally invasive and benign surgical characteristics. However, as Freeman's legacy came into disrepute, so did the transorbital brain access corridor, again resulting in its stunted evolution. Monomethyl auristatin E chemical structure Microsurgery and endoscopy further influenced the use, or lack thereof, of the transorbital corridor in neurosurgical approaches.
