Factors Affecting Recurrence and Survival in Stage IIA Colon Cancer Patients.

INTRODUCTION: Our study delves into the intricate interplay of risk factors and the strategic selection of adjuvant therapy, scrutinizing their influence on recurrence and survival outcomes in stage IIA (T3N0M0) colon cancer patients. MATERIALS AND METHODS: The study examined the medical records of patients who underwent surgery for stage IIA colon cancer. Identification of stage IIA (pT3N0M0) colon cancer involved a comprehensive review of postoperative clinical records and histological reports. Parameters such as demographic data, tumor characteristics, microsatellite instability status, tumor locations, recurrence risk factors, preoperative carcinoembryonic antigen levels, and adjuvant treatments were systematically evaluated. RESULTS: In our study involving 220 patients, 138 were male (62.7%), with a median age of 62 years and a median body mass index of 25.1 kg/m2. In the patient group without risk factors, no statistically significant difference was detected in disease-free survival (DFS) rates between those who received treatment and those who did not (p = 0.546). DFS rates of patients with >1 risk factor were statistically significantly lower than those with a single risk factor (p = 0.017). In patients with >1 risk factor, the DFS of those who did not receive adjuvant treatment was significantly lower than those who received adjuvant treatment (p < 0.001). In the patient group with recurrence, when adjuvant treatments were considered, recurrence was significantly higher in the group receiving capecitabine (p = 0.01). CONCLUSION: The decision for adjuvant chemotherapy in stage IIA colon cancer patients involves careful consideration of various parameters and risk factors. The evolving landscape of research may refine recommendations, ensuring optimal treatment outcomes while minimizing unnecessary toxicity.

Prognostic Value of Inflammation And Nutrition-Based Scores in Non-Small Cell Lung Cancer.

OBJECTIVE: In studies conducted on non-small cell lung cancer (NSCLC) patients, many factors such as age, stage, weight loss, lymph node, and pleural involvement have been shown to affect survival. On the other hand, systemic inflammation plays a critical role in proliferation, migration, invasion, and metastasis. Inflammation and nutrition-based prognostic scores are reported to be associated with survival in patients with NSCLC. The aim of our study is to show the effects of these scores on survival and disease progression in NSCLC patients. SUBJECTS AND METHODS: Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), modified Glasgow prognostic score (mGPS), and prognostic nutritional index (PNI) values in 102 patients with stage 1,2 and 3A NSCLC were analyzed retrospectively. RESULTS: NLR (p < 0.001), PLR (p = 0.001), PNI (p < 0.001), and mGPS (p = 0.001) variables showed a statistically significant difference according to mortality groups. NLR and PLR values were higher in exitus patients. However, PNI values were higher in surviving patients. NLR (p < 0.001), PLR (p = 0.004), PNI (p = 0.001), and mGPS (p = 0.015) variables showed a statistically significant difference in terms of locoregional recurrence. PNI (p = 0.001) and mGPS (p = 0.001) in terms of distant metastasis development during follow-up and treatment, showed a statistically significant difference. CONCLUSION: NLR, PLR, PNI, and mGPS are easily accessible and non-invasive parameters and provide predictive information about survival and disease course. We showed the effect of these parameters on the prognosis.

Late-onset familial mediterranean fever: single-center experience and literature review.

Familial Mediterranean fever (FMF) is a hereditary, autoinflammatory disease characterized by recurrent fever and serositis attacks. The disease onset occurs before 20 years of age in 90% of patients and rarely after the 4th decade. The aim of this study is to screen our FMF patient pool for patients with disease onset after age of 40 and to compare them to patients with early onset with regard to clinical and genetic features. The charts of 2020 patients registered in our FMF center in the years 2008-2017 were screened with regard to age of disease onset. Patients with disease onset after the age of 40 were considered as late-onset group (Group 1). The control group (Group 2) consisted of patients with a disease onset before the age of 20 who were randomly selected from the patient pool with twice the number of probands. Demographic, clinical and genetic data were recorded. Out of 2020 patients, the attacks of FMF had started after the fourth decade in 41 patients (2.02%), (Group 1). The male to female ratio was 1:1.7 in both groups. The delay of diagnosis was 5.6 ± 5.75 years in group 1, 10.7 ± 12.3 years in group 2. The only significant difference with regard to clinical features between two groups was the frequency of fever, which was present in 26 (63.4%) patients in group 1 and 67 (81.7%) in group 2 (p = 0.026). M694V mutation was more prevalent among early-onset group whereas exon 2 variants were more frequent in patients with late onset. The mean colchicine dose in the last 6 months was 1.38 ± 0.64 mg in group 1, and 1.61 ± 0.47 mg in group 2. FMF may start after 40 years of age in approximately 2% of the patients. Lower frequency of fever, lower daily colchicine dose and lower prevalence of exon 10 mutations point out that FMF patients with a disease onset after 40 years of age experience a milder disease compared to those with an onset before the second decade of life.

May dexpanthenol, platelet-rich plasma, and thymoquinone provide new hope to maintain liver regeneration after partial hepatectomy?

BACKGROUND/AIMS: Complete liver regeneration may not always be possible after liver injuries and/or partial liver resection. The present study investigated the effects of dexpanthenol, platelet-rich plasma (PRP), and thymoquinone on liver regeneration in rats after partial hepatectomy (PH). MATERIALS AND METHODS: A total of 34 Wistar albino rats, each weighing 250-280 g, were randomly separated into four groups. PH was performed, and except for the control group, intraperitoneal dexpanthenol, PRP, or thymoquinone was administered to the relevant groups for 7 days. All rats were then sacrificed, and the liver tissues were examined histopathologically and biochemically. RESULTS: PRP reduced all oxidant-antioxidant parameters in rats that experienced liver regeneration, but did not create histopathological improvement in the liver tissue. Dexpanthenol had a histopathological improving effect on the liver tissue, but had no effect on biochemical parameters. Thymoquinone showed no histopathological or biochemical effects on liver regeneration. CONCLUSION: Although dexpanthenol did not affect biochemical oxidative parameters, it was considered to have improving effects on liver regeneration histopathologically. In addition, it was thought that PRP may be used for treatment of ischemia-reperfusion injury and cholestatic damage of the liver. Nevertheless, further studies are required on these subjects.

Comparison of Fatal Injuries Resulting from Tractor and High Speed Motorcycle Accidents in Turkey: A Multicenter Study.

AIM: Injuries are among the main causes of mortality and morbidity all over the world, and effective initial triage of these patients can determine the thin line between death and life. Tractor accidents and related injuries are significant problems particularly in rural areas. However, major trauma classification systems do not include tractor accidents as a criterion for trauma team activation or transportation of the patients to a trauma center. This study evaluated the general characteristics and outcomes of tractor accidents in comparison to motorcycle accidents, which are considered as a comparison criterion for major trauma. MATERIALS AND METHODS: This is a multicenter study conducted in 6 emergency departments in 4 cities over a six month period. All cases over 18 years of age who were admitted to emergency service due to tractor or motorcycle accidents and meet the criteria were included in the study. The general characteristics and outcomes of both trauma types were compared to determine whether tractor accident should be considered as major traumas. RESULTS: Eighty-eight patients had a tractor accident, and 339 patients had a motorcycle accident. The tractor accident victims were significantly younger (p<0.001), and the proportion of females was higher in this group (p=0.001). Glasgow coma score (p=0.062), revised trauma score (p=0.201), duration from incident to admission (p=0.481), and route of admission (p=0.810) were similar between both accident types. The rates of thoracic traumas (42% versus 23%, p<0.001) and spinal injuries (17% versus 5.9%, p=0.002) were significantly higher in tractor accidents. The hospitalization rates of the patients were significantly higher in tractor accidents (p=0.008). CONCLUSION: The findings of this study support the hypothesis that tractor accidents should be included in the criteria of ATLS major trauma classification system and trauma team activation procedures.
