RESUMO
The treatment of stage III non-small cell lung cancer (NSCLC) is complex. Here, we aimed to examine the prognostic utility of sarcopenia and metabolic muscle volumes and evaluate their relationship with oncological treatments in patients with locally advanced NSCLC. Patients with unresectable stage III NSCLC were evaluated retrospectively. Muscle fields were measured, and metabolic parameters of the psoas were obtained. The skeletal muscle index (SMI), sarcopenia, sarcopenic obesity, and body mass index (BMI)-associated sarcopenia were evaluated. Fifty-three (94.6%) patients were men, and three (5.4%) were women. Sarcopenia was identified in 36 (64.3%) patients. Pretreatment sarcopenia and BMI-associated sarcopenia negatively affected overall survival (p = 0.040 and 0.023, respectively). A high psoas SUVmean (Standardized Uptake Value mean) and low mean psoas HU (Hounsfield unit) were poor prognostic factors (p = 0.009 and 0.014, respectively). SMI and muscle mass decreased after oncological treatment. Advanced age, inability to complete treatment, administration of chemoradiotherapy after chemotherapy, presence of sarcopenia, and a low mean psoas HU decreased survival. In conclusion, sarcopenia and BMI-associated sarcopenia are poor prognostic factors in patients with lung cancer. Oncological treatments can adversely affect muscle mass. The metabolic parameters of the psoas muscle can predict patient prognosis.

Introduction Cancer patients are among the groups at high risk in the COVID-19 pandemic. Here, we aimed to determine the effectiveness of neoadjuvant chemotherapy (NACT) during the pandemic period and examine the prognostic factors in patients with non-small cell lung cancer (NSCLC). Method Patients with stage I-III NSCLC were treated in our hospitals between 2020-2022. Treatment responses were evaluated in patients who underwent NACT. Prognostic factors and the nutritional and inflammatory indexes were investigated. Results Thirty-eight patients received NACT. 57.9% of patients were stage-III. The objective response rate was 57.9%. Pathological complete response was obtained in 10.5% of patients. No prognostic role of inflammatory indices was determined. 21.1% of patients developed a COVID-19 infection. Disease-free survival was 19 months. Survival decreased with large tumor size and presence of metastasis. Conclusion NACT has high response rates. NACT can be used as bridging therapy in suitable patients whose surgery is postponed during the pandemic period.
RESUMO
OBJECTIVES: Black cumin is widely used as a spice and as a traditional treatment. The active ingredient in black cumin seeds is thymoquinone. Thymoquinone has shown anticancer effects in some cancers. We planned to investigate its anticancer effect on pancreatic cancer cell lines. METHODS: Thymoquinone chemical component in various doses was prepared and inoculated on pancreatic cancer cell culture, healthy mesenchymal stem cells, and peripheral blood mononuclear cell culture. IC50 values were calculated by absorbance data and measuring cell viability by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide staining of cells incubated with thymoquinone at 24, 48, and 72 h. RESULTS: There was dose-related cytotoxicity. Maximal cytotoxicity was observed at 24 h and 100 µM thymoquinone concentrations in pancreatic cancer cell culture and mesenchymal stem cells. Any concentration of thymoquinone was not cytotoxic to peripheral blood mononuclear cell. Thymoquinone even caused proliferation at a concentration of 6.25 µM. CONCLUSIONS: Since the cytotoxic concentration of thymoquinone on pancreatic cancer cell culture and mesenchymal stem cells is the same, it is not appropriate to use thymoquinone to achieve cytotoxicity in pancreatic cancer. However, since thymoquinone provides proliferation in peripheral blood mononuclear cell at a noncytotoxic dose, it may have an immune activator effect. Therefore, in vivo studies are needed to investigate the effect of thymoquinone on the immune system.

Genitourinary system lymphomas comprise a small part of extra-nodal lymphomas (ENLs). ENLs of uterine origin are extremely rare and are often confused with gynecological malignancies. We present an 80-year-old female patient diagnosed with diffuse large B-cell lymphoma (DLBCL) with a single focus of the uterus. The patient's only complaint was abnormal uterine bleeding. Magnetic resonance imaging revealed an intramural-subserous-submucous multiple mass lesion with minimal contrast enhancement mimicking leiomyosarcoma. Diffuse pathological 18F-fluorodeoxyglucose uptake was detected in the entire uterus corpus and cervix on positron emission tomography/computed tomography (PET/CT) scanning. The pathology of the endocervical and endometrial curettage material obtained was DLBCL; the patient was diagnosed with ENL, and a single focus was the uterus. ENLs should be considered in the differential diagnosis of gynecological malignancies in patients with abnormal uterine bleeding. PET/CT is crucial in showing metabolically active spread areas in these patients.

RESUMO
OBJECTIVE: To evaluate the effect of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) values of the primary tumor measured by preoperative positron emission tomography/computed tomography (FDG-PET/CT) on survival in patients with operated non-small cell lung cancer (NSCLC). STUDY DESIGN: Cohort study. PLACE AND DURATION OF STUDY: Recep Tayyip Erdogan University, Faculty of Medicine, Department of Medical Oncology from January 2017 to June 2020, Turkey. METHODOLOGY: Patients with operated NSCLC were reviewed retrospectively. Metabolic parameters of FDG-PET/CT such as pathological tumor features, type of operation, MTV/TLG values, and whether they received adjuvant therapy were evaluated. Disease-free survival (DFS) and overall survival (OS) times were calculated. RESULTS: Most of the 77 patients (96.1%) were male. The mean age is 64±8 years. Lobectomy was performed in 66 (85.7%) patients, and pneumonectomy was performed in 11 (14.3%) patients. The mean tumor diameter was 3.7±2.015cm. Squamous cell carcinoma was detected in 37 patients (48.1%) and adenocarcinoma in 35 patients (45.5%). Thirty-eight patients (49.4%) received adjuvant chemotherapy. SUVmax, MTV, and TLG values of the primary tumor were high in patients under 65 years of age and with a tumor diameter of ≥3cm. DFS was nine months (4.5-18), and OS was 19 months (11-29). The 2-year survival rate was 75.6%. It was observed that patients with adenocarcinoma relapsed more frequently, which negatively affected survival (p=0.023, and p=0.024 respectively). High MTV (p=0.01) and TLG (p=0.015) values were associated with poor prognosis. CONCLUSION: NSCLC is a heterogeneous disease, and survival is affected by many factors. Our study showed that the subtype of adenocarcinoma and high MTV and TLG values of the primary tumor are poor prognostic factors in operated early-stage lung cancers. KEY WORDS: Early-stage, Non-small cell lung cancer, MTV, TLG, NSCLC, Survival, FDG-PET/CT.

Regorafenib is a multikinase inhibitor. It is used for metastatic colorectal cancer (mCRC) treatment. It has a mild effect. Regorafenib outcomes, and side effects may vary across patients. This study was aimed to evaluate the factors that affect regorafenib outcomes in mCRC patients. We conducted a single-center and retrospective study. Fifty-six patients were included. All patients had received regorafenib for mCRC. Some clinical and pathological factors and the effects of these factors on overall survival (OS), progression-free survival (PFS), and disease control rates (DCR) were analyzed. Concomitant amlodipine intake with regorafenib improved OS [14.26 vs. 6.97 months; 95% confidence interval, 4.04-20.84; P = 0.031] and DCR at 12th week (90% vs. 46%; P = 0.012). Hepatic metastasis was found as the poorest prognostic factor in both univariate and multivariate analyses. Patients who received chemotherapy after regorafenib had better OS. Good performance status was the strongest indicator of better OS. Patients taking amlodipine for arterial hypertension at the same time with regorafenib had numerically better OS and PFS and statistically better DCR. Amlodipine itself already has anticancer effects, and it has additive anticancer effects with regorafenib. The presence of hepatic metastases was found to be the most important prognostic factor for OS. There were not any predictive factors of side effects to regorafenib.

BACKGROUND: Art, as a product of human behavior, is the expression of emotions from inner states and may provide catharsis, purification, and release. Several branches of art, most notably music, dance, and painting, can be used for treatment purposes, especially in the case of psychological disorders. Cancer, which is defined as uncontrolled cell growth, has been an important health issue throughout history, but the recent increase in its frequency has made it one of the most significant public health problems. Both the physiological distress the disease subjects the body to and the accompanying emotional distress are important factors to be considered in cancer treatment. AIMS: In this study, the role of art in expressing emotions of oncological patients was investigated. MATERIALS AND METHODS: During the treatment period, patients were interviewed about their experiences, feelings, expectations and perceptions. The picture was used as an expression of emotions. RESULTS: Communication between the patient and doctor is one of the most important elements in the treatment process, and it has come to the fore in branches of medicine, such as oncology, because of its positive contribution to treatment compliance. In general, the study showed a pronounced positivity and expectations on the part of patients from the hope-life-healing process rather than oncological treatment. CONCLUSION: In this study, we aim to demonstrate how the artistic expression of emotions, in particular, through painting, has a positive effect on healing, hope, and the interactions between cancer patients under oncological treatment and medical professionals.
