ABSTRACT

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, MSI status, tumor locations, recurrence risk factors, preoperative CEA 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 (BMI) of 25.1 kg/m². In the patient group without risk factors, no statistically significant difference was detected in DFS rates between those who received treatment and those who did not (p=0.546). DFS rates of patients with >1 risk factor were found to be 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 observed to be 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.

ABSTRACT

The only phase 3 study on the effectiveness of CDK 4-6 inhibitors in first-line treatment in premenopausal patients with hormone receptor (HR) positive, HER2 negative metastatic breast cancer is the MONALEESA-7 study, and data on the effectiveness of palbociclib is limited. Data are also limited regarding the effectiveness of CDK 4-6 inhibitors in patients whose dose was reduced due to neutropenia, the most common side effect of CDK 4-6 inhibitors. In our study, we aimed to evaluate the effectiveness of palbociclib and ribociclib in first-line treatment in patients with premenopausal metastatic breast cancer and the effect of dose reduction due to neutropenia on progression-free survival. Our study is a multicenter, retrospective study, and factors affecting progression-free survival (PFS) were examined in patients diagnosed with metastatic premenopausal breast cancer from 29 different centers and receiving combination therapy containing palbociclib or ribociclib in the metastatic stage. 319 patients were included in the study. The mPFS for patients treated with palbociclib was 26.83 months, and for those receiving ribociclib, the mPFS was 29.86 months (p = 0.924). mPFS was 32.00 months in patients who received a reduced dose, and mPFS was 25.96 months in patients who could take the initial dose, and there was no statistical difference (p = 0.238). Liver metastasis, using a fulvestrant together with a CDK 4-6 inhibitor, ECOG PS 1 was found to be a negative prognostic factor. No new adverse events were observed. In our study, we found PFS over 27 months in patients diagnosed with premenopausal breast cancer with CDK 4-6 inhibitors used in first-line treatment, similar to post-menopausal patients. We did not detect any difference between the effectiveness of the two CDK 4-6 inhibitors, and we showed that there was no decrease in the effectiveness of the CDK 4-6 inhibitor in patients whose dose was reduced due to neutropenia.

ABSTRACT

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.
