Abstract
Ovarian cancer is a leading cause of death among gynecologic tumors, often detected at advanced stages. Metabolic reprogramming and increased lipid biosynthesis are key factors driving cancer cell growth. Stearoyl-CoA desaturase 1 (SCD1) is a crucial enzyme involved in de novo lipid synthesis, producing mono-unsaturated fatty acids (MUFAs). Here, we aimed to investigate the expression and significance of SCD1 in epithelial ovarian cancer (EOC). Comparative analysis of normal ovarian surface epithelial (NOSE) tissues and cell lines revealed elevated SCD1 expression in EOC tissues and cells. Inhibition of SCD1 significantly reduced the proliferation of EOC cells and patient-derived organoids and induced apoptotic cell death. Interestingly, SCD1 inhibition did not affect the viability of non-cancer cells, indicating selective cytotoxicity against EOC cells. SCD1 inhibition on EOC cells induced endoplasmic reticulum (ER) stress by activating the unfolded protein response (UPR) sensors and resulted in apoptosis. The addition of exogenous oleic acid, a product of SCD1, rescued EOC cells from ER stress-mediated apoptosis induced by SCD1 inhibition, underscoring the importance of lipid desaturation for cancer cell survival. Taken together, our findings suggest that the inhibition of SCD1 is a promising biomarker as well as a novel therapeutic target for ovarian cancer by regulating ER stress and inducing cancer cell apoptosis.

Impact of Coronavirus Disease 2019 on Gastric Cancer Diagnosis and Stage: A Single-Institute Study in South Korea. J Gastric Cancer 2023; 23:574-583.

Abstract
PURPOSE Gastric cancer (GC) is among the most prevalent and fatal cancers worldwide. National cancer screening programs in countries with high incidences of this disease provide medical aid beneficiaries with free-of-charge screening involving upper endoscopy to detect early-stage GC. However, the coronavirus disease 2019 (COVID-19) pandemic has caused major disruptions to routine healthcare access. Thus, this study aimed to assess the impact of COVID-19 on the diagnosis, overall incidence, and stage distribution of GC. MATERIALS AND METHODS We identified patients in our hospital cancer registry who were diagnosed with GC between January 2018 and December 2021 and compared the cancer stage at diagnosis before and during the COVID-19 pandemic. Subgroup analyses were conducted according to age and sex. The years 2018 and 2019 were defined as the "before COVID" period, and the years 2020 and 2021 as the "during COVID" period. RESULTS Overall, 10,875 patients were evaluated; 6,535 and 4,340 patients were diagnosed before and during the COVID-19 period, respectively. The number of diagnoses was lower during the COVID-19 pandemic (189 patients/month vs. 264 patients/month) than before it. Notably, the proportion of patients with stages 3 or 4 GC in 2021 was higher among men and patients aged ≥40 years. CONCLUSIONS During the COVID-19 pandemic, the overall number of GC diagnoses decreased significantly in a single institute. Moreover, GCs were in more advanced stages at the time of diagnosis. Further studies are required to elucidate the relationship between the COVID-19 pandemic and the delay in the detection of GC worldwide.

Pattern of practice for postoperative management of endometrial cancer in Korea: a survey by the Korean Gynecologic Oncology Group and the Korean Radiation Oncology Group (KGOG 2028-KROG 2104).

Abstract
OBJECTIVE This study aimed to investigate the current status of postoperative management of uterine endometrial cancer (EC) in Korea. METHODS A mail survey was administered to members of the Korean Gynecologic Oncology Group and Korean Radiation Oncology Group. A total of 38 gynecologic cancer surgeons (GYNs) and 31 radiation oncologists (RO) in 43 institutions was responded. The questionnaire consisted of general questions for clinical decision and clinical case questions. The GYN and RO responses were compared using chi-square statistics. RESULTS The 2 expert groups had similar responses for clinical decision based on the results of the Gynecologic Oncology Group (GOG)-249 and Postoperative Radiation Therapy for Endometrial Carcinoma-III trials in the early-stage EC. In contrast, the responses based on GOG-258 results differed, as GYNs most frequently opted for sequential chemotherapy (CTx) and radiotherapy (RT), while ROs preferred concurrent chemoradiotherapy in locally advanced stage (p<0.05). Based on the GOG-258, GYNs preferred CTx alone for adjuvant treatment of serous or clear cell adenocarcinoma histology, whereas ROs advocated for combined CTx and RT (sequential or concurrent). Among the clinical case questions, GYNs were more likely than ROs to choose CTx alone rather than the combination of CTx and RT (sequential or concurrent) as the answers to case questions representing patients with locally advanced stage or unfavorable histology (all p<0.05). CONCLUSION The present study showed several different opinions of GYNs and ROs regarding adjuvant treatment for EC, particularly for adjuvant RT in advanced stage or unfavorable histology.
