Hemoglobin, albumin, lymphocyte, and platelet score as a predictor of prognosis in metastatic gastric cancer.

BACKGROUND: The hemoglobin, albumin, lymphocyte, and platelet (HALP) score, derived from a composite evaluation of markers reflecting the tumor-inflammation relationship and nutritional status, has been substantiated as a noteworthy prognostic determinant for diverse malignancies. AIM: To investigate how the HALP score relates to prognosis in patients with metastatic gastric cancer. METHODS: The cutoff values for the HALP score, neutrophil/lymphocyte ratio, and platelet/lymphocyte ratio were determined using receiver operating characteristic analysis. Low HALP scores were defined as those less than 24.79 and high HALP scores as those greater than 24.79. RESULTS: The study cohort comprised 147 patients and 110 of them (74.8%) were male. The patients' median age was 63 (22-89) years. The median overall survival was significantly superior in the patients with high HALP scores than in those with low HALP scores (10.4 mo vs 7.5 mo, respectively; P < 0.001). CONCLUSION: The HALP score was found to be a prognostic factor in patients with metastatic gastric cancer.

Second-line Chemotherapy in Advanced Gastric Cancer: Taxanes versus 5-FU-Based Treatment.

OBJECTIVE: To determine the comparative efficacy of taxane-based treatment and 5-FU-based treatment as second-line chemotherapy regimens in advanced gastric cancer patients, as measured by overall survival (OS) and progression-free survival (PFS). STUDY DESIGN: Observational study. Place and Duration of the Study: Department of Medical Oncology, Health Science University Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkiye, from January 2008 and December 2020. METHODOLOGY: Patients aged 18 years and older, diagnosed with gastric cancer, who received at least one line chemotherapy were included. Patients who received FOLFIRI, FOLFOX, and capecitabine in the second-line therapy were grouped as those who received 5-FU-based treatment, while those who received docetaxel and paclitaxel were grouped as those who received taxan-based treatment. The primary outcome measures, OS and PFS, were assessed and compared between the treatment groups using the Kaplan-Meier method. RESULTS: A total of 172 patients were included in this analysis, among whom 73 (42.4%) received second-line chemotherapy. Among the patients who received the second-line treatment, 50 (68.5%) were males. The median age of the cohort was 60 years (23-86), with 37 (50.7%) patients falling into the <60 age group. The overall response rates (ORR) were 8% (2/25) in the taxane group and 16.7% (8/48) in the 5-FU-based treatment group. The median overall survival (OS) for all patients receiving second-line therapy was 7.52 months (standard error: 0.97; 95% confidence interval [CI]: 5.62-9.43). Specifically, the median OS was 5.16 months (standard error: 1.07; 95% CI: 3.07-7.25) in the taxane group and 8.02 months (standard error: 1.40; 95% CI: 5.28-10.75) in the group receiving 5-FU-based therapy (p=0.11). CONCLUSION: The superiority of chemotherapy regimens to each other could not be demonstrated. However, the second-line treatment demonstrated clear superiority over the best supportive care. Therefore, it is recommended that all patients with good performance status (PS) should be offered second-line treatment.

Treatment efficacy of ribociclib or palbociclib plus letrozole in hormone receptor-positive/HER2-negative metastatic breast cancer.

Background: Ribociclib, palbociclib and abemaciclib are currently approved CDK4/6 inhibitors along with aromatase inhibitors as the first-line standard-of-care for patients with hormone receptor-positive, HER2-negative metastatic breast cancer. Methods: The authors report retrospective real-life data for 600 patients with estrogen receptor- and/or progesterone receptor-positive and HER2-negative metastatic breast cancer who were treated with ribociclib and palbociclib in combination with letrozole. Results & conclusion: The results demonstrated that the combination of palbociclib or ribociclib with letrozole has similar progression-free survival and overall survival benefit in real life for the patient group with similar clinical features. Specifically, endocrine sensitivity may be a factor to be considered in the treatment preference.

Real life experience of patients with locally advanced gastric and gastroesophageal junction adenocarcinoma treated with neoadjuvant chemotherapy: a Turkish oncology group study.

Neoadjuvant chemotherapy (NACT) in gastroesophageal junction (GEJ) and gastric cancer (GC) was shown to improve survival in recent studies. We aimed to share our real-life experience of patients who received NACT to compare the efficacy and toxicity profile of different chemotherapy regimens in our country. This retrospective multicentre study included locally advanced GC and GEJ cancer patients who received NACT between 2007 and 2021. Relation between CT regimens and pathological evaluation were analysed. A total of 794 patients from 45 oncology centers in Turkey were included. Median age at the time of diagnosis was 60 (range: 18-86). Most frequent NACT regimens used were FLOT (65.4%), DCF (17.4%) and ECF (8.1%), respectively. In the total study group, pathological complete remission (pCR) rate was 7.2%, R0 resection rate 86.4%, and D2 dissection rate was 66.8%. Rate of pCR and near-CR (24%), and R0 resection (84%) were numerically higher in FLOT arm (p > 0.05). Patients who received FLOT had also higher chemotherapy-related toxicity rate compared to patients who received other regimens (p > 0.05). Median follow-up time was 16 months (range: 1-154 months). Estimated median overall survival (OS) was 58.4months (95% CI: 35.2-85.7) and disease-free survival (DFS) was 50.7 months (95% CI: 25.4-75.9). The highest 3-year estimated OS rate was also shown in FLOT arm (68%). We still do not know which NACT regimen is the best choice for daily practice.  Clinicians should tailor treatment regimens according to patients' multifactorial status and comorbidities for to obtain best outcomes. Longer follow-up period needs to validate our results.

Efficacy and safety of folfiri plus aflibercept in second-line treatment of metastatic colorectal cancer: Real-life data from Turkish oncology group.

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience. Materials and Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study. The clinical and pathological features of the patients were recorded retrospectively. Survival (overall and progression-free survival [PFS]), response rates, and safety data were analyzed. Results: The median age was 61. Majority of patients (87.5%) received first-line bevacizumab and 10.1% of patients received anti-epidermal growth factor receptor agents. About 80% of patients had KRAS, 18.6% of patients had NRAS, and 6.4% of patients had BRAF mutations. The median OS was 11.6 months (95% confidence interval [CI], 10.6-12.6) and the median PFS was 6 months (95% CI, 5.5-6.5). About 4.6% of patients had complete response and 30.6% of patients had partial response as best tumor response. Grade 1-2 toxicities were seen in 33.4% of patients, while grade 3-4 toxicities were recorded in 27% of patients. Eight patients (2%) died due to treatment toxicity. Conclusions: Overall and PFS were similar in routine clinical practice compared to phase III pivotal VELOUR trial. However, response rates were found to be higher. It was observed that there were fewer adverse events compared to the VELOUR trial.

Prognostic factors of perioperative FLOT regimen in operable gastric and gastroesophageal junction tumors: real-life data (Turkish Oncology Group).

BACKGROUND: Perioperative FLOT regimen is a standard of care in locally advanced operable gastric and GEJ adenocarcinoma. We aimed to determine the efficacy, prognostic factors of perioperative FLOT chemotherapy in real-life gastric and GEJ tumors. METHODS: The data of patients who were treated with perioperative FLOT chemotherapy were retrospectively analyzed from 34 different oncology centers in Turkey. Baseline clinical and demographic characteristics, pretreatment laboratory values, histological and molecular characteristics were recorded. RESULTS: A total of 441 patients were included in the study. The median of age our study population was 60 years. The majority of patients with radiological staging were cT3-4N(+) (89.9%, n = 338). After median 13.5 months (IQR: 8.5-20.5) follow-up, the median overall survival was NR (95% CI, NR to NR), and median disease free survival was 22.9 (95% CI, 18.6 to 27.3) months. The estimated overall survival at 24 months was 62%. Complete pathological response (pCR) and near pCR was achieved in 23.8% of all patients. Patients with lower NLR or PLR have significantly longer median OS (p = 0.007 and p = 0.033, respectively), and patients with lower NLR have significantly longer median DFS (p = 0.039), but PLR level did not affect DFS (p = 0.062). The OS and DFS of patients with better ECOG performance scores and those who could receive FLOT as adjuvant chemotherapy instead of other regimens were found to be better. NLR was found to be independent prognostic factor for OS in the multivariant analysis. At least one adverse event reported in 57.6% of the patients and grade 3-4 toxicity was seen in 23.6% patients. DISCUSSION: Real-life perioperative FLOT regimen in operable gastric and GEJ tumors showed similar oncologic outcomes compared to clinical trials. Better performance status, receiving adjuvant chemotherapy as same regimen, low grade and low NLR and PLR improved outcomes in real-life. However, in multivariate analysis, only NLR affected OS.

The relation between inflammation-based parameters and survival in metastatic pancreatic cancer.

AIM: We aimed to evaluate whether tumor markers and inflammation parameters effect on survival in patients with metastatic pancreatic cancer (MPC). PATIENTS AND METHODS: This retrospective analysis included 170 patients with pancreatic cancer who were admitted to the oncology clinic at the metastatic stage. Basic patient demographic characteristics, chemotherapy (CT) that patients received in the first line, complete blood count, neutrophil/lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), albumin/globulin ratio (AGR), prognostic nutritional index (PNI), tumor markers (carcinoembryonic antigen [CEA], carbohydrate antigen 19-9 [CA19-9]), and survival were analyzed. Receiver operating characteristic analysis was used to determine the optimum cutoff value of NLR, PLR, AGR, PNI, CEA, and CA 19-9, which could predict survival. RESULTS: The median age of the patients was 63 years (range, 33-87). About 63.5% of the patients were male and 44.5% were female. 161 (94.7%) patients died, and the median overall survival (OS) was 8.0 months (95% confidence interval = 6.6-9.4) for all patients. In univariate analysis, age (P < 0.001), CT regime (P < 0.002), AGR (P < 0.006), PNI (P < 0.017), NLR (P < 0.001), PLR (P < 0.062), and CA19-9 (P < 0.002) were statistically significant. In multivariate analysis, age (hazard ratio [HR] 1.534 95% 1.079-2.182 P < 0.017) CA19-9 (HR1.410 95% 1.001-1.989, P ≤0.005) and, NLR (HR 1.569 95% 1.001-2.463, P < 0.049) were significant. CONCLUSION: We determined, age, CA19-9, and basal high NLR as independent adverse prognostic factors for OS in APC. Fluorouracil, leucovorin, irinotecan, and oxaliplatin CT resulted in a significant increase in OS.

Hypertrichosis, trichomegaly, and androgenic alopecia related to cetuximab treatment.

Anti-epidermal growth factor receptor (EGFR) antibodies are mainly used in the treatment of advanced stages of solid tumors as a targeted therapy to inhibit tumor proliferation. They cause many dermatological adverse reactions through inhibition of EGFR pathway in the skin. A 39-year-old female patient diagnosed with metastatic colon adenocarcinoma received oxaliplatin, fluorouracil, and folinic acid regimen with cetuximab. The patient noticed increase in fairy hair especially at facial area as well as in the whole body beginning after the first few cycles of treatment, after 3 months. Obvious hypertrichosis, androgenic alopecia, and trichomegaly were observed. Blood tests for androgenetic alopecia and hirsutism were studied. Hormonal levels were in normal range. Upper abdominal imaging to rule out any adrenal lesion was also normal. Previous studies reported found that cetuximab may cause alopecia, hypertrichosis on face and body, and trichomegaly. We have not encountered a combination of hypertrichosis, androgenic type alopecia, and trichomegaly in the literature.
