RESUMEN
Metastatic castration-resistant prostate cancer (mCRPC) remains a challenging condition to treat despite recent advancements. This retrospective study aimed to assess the activity and tolerability of Lutetium-177 (Lu-177) PSMA-617 radioligand therapy (RLT) in mCRPC patients across multiple cancer centers in Turkey. The study included 165 patients who received at least one cycle of Lu-177 PSMA-617 RLT, with the majority having bone metastases and undergone prior treatments. Prostate-specific antigen (PSA) levels were assessed before each treatment cycle, and the biochemical response was evaluated in accordance with the Prostate Cancer Work Group 3 Criteria. The PSA decline of ≥50% was classified as a response, while an increase of ≥25% in PSA levels was indicative of progressive disease. Neither response nor progression was considered as stable disease. The Lu-177 PSMA-617 RLT led to a significant PSA response, with 50.6% of patients achieving a >50% decrease in PSA levels. Median overall survival (OS) and progression-free survival were 13.5 and 8.2 months, respectively. Patients receiving Lu-177 PSMA-617 RLT in combination with androgen receptor pathway inhibitors (ARPIs) had a higher OS compared to those receiving Lu-177 PSMA-617 RLT alone (18.2 vs 12.3 months, P = .265). The treatment was generally well-tolerated, with manageable side effects such as anemia and thrombocytopenia. This study provides real-world evidence supporting the effectiveness and safety of Lu-177 PSMA-617 RLT in mCRPC patients, particularly when used in combination with ARPIs. These findings contribute to the growing body of evidence on the potential benefits of PSMA-targeted therapies in advanced prostate cancer.

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is extensively employed in breast cancer (BC), primarily for aggressive subtypes like triple-negative and human epidermal growth factor receptor 2 (HER2)-positive BC and in estrogen receptor-positive (ER+)/HER2- BC with high-risk features. In ER+/HER2- BC, pathological complete rates are much lower (<10%), while axillary dissection rates are higher. This study focuses on hormone receptor-positive (HR+)/HER2- BC patients undergoing NAC, examining its impact on pathological complete response (pCR) rates, with specific attention to tumor Ki67 and ER status. METHODS: Retrospective data analysis from Kartal Dr. Lütfi Kirdar City Hospital included HR+/HER2- BC patients who received NAC. Clinicopathological factors, NAC response, and surgical outcomes were assessed. Statistical analyses evaluated the association between Ki67, ER status, and pCR. RESULTS: Of 203 patients, 11.8% achieved pCR. Ki67 (p < 0.001) and ER percentage (p < 0.001) significantly correlated with pCR. Higher Ki67 was associated with increased pCR likelihood (HR: 1.03, 95% CI: 1.01-1.05). A Ki67-pCR probability curve revealed a cutoff of 23.5%. ER%-pCR analysis showed decreasing pCR rates with higher ER percentages. Multivariate analysis confirmed Ki67 (p = 0.003, HR: 1.02) and ER percentage (p = 0.019, HR: 0.97) as independent predictors of pCR probability. CONCLUSION: Consideration of Ki67 and ER percentage aids in NAC decisions for HR+/HER2- BC, identifying patients with high NAC response rates, facilitating axillary preservation, and potentially avoiding axillary dissection. The pCR rates in patients with Ki67 ≤24 are particularly low, especially in patients with a high ER percentage. In these cases, upfront surgery and adjuvant treatment should be considered instead of NAC.

OBJECTIVES: Head and neck cancers (HNCs) represent a significant global health concern due to high morbidity and mortality rates. Despite therapeutic advances, the prognosis for advanced or recurrent cases remains challenging. Nivolumab obtained approval for recurrent or metastatic HNC based on the Phase III CheckMate 141 trial. This study aimed to evaluate the real-world outcomes of nivolumab in patients with non-nasopharyngeal HNC. DESIGN: In this multicenter retrospective study, we analyzed 124 patients with recurrent or metastatic non-nasopharyngeal HNC who received nivolumab in the second-line setting and beyond. Data were collected from 20 different cancer centers across Turkey. The effectiveness and safety of the treatment and survival outcomes were evaluated. RESULTS: Nivolumab exhibited favorable clinical responses, yielding an objective response rate of 29.9% and a disease control rate of 55.7%. Safety assessments revealed a generally well-tolerated profile, with no instances of treatment discontinuation or mortality due to side effects. Survival analysis disclosed a median overall survival (OS) of 11.8 (95% CI 8.4-15.2) months. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 1.64, p = 0.045), laryngeal location (HR: 0.531, p = 0.024), and neutrophil-to-lymphocyte ratio > 3.5 (HR: 1.97, p = 0.007) were independent predictors of OS. CONCLUSIONS: Nivolumab is an effective and safe treatment option for patients with recurrent or metastatic non-nasopharyngeal HNC in real-world settings. Further studies are needed on factors affecting response to treatment and survival outcomes.
RESUMEN
Background and Objectives: Lung cancer is the leading cause of cancer-related deaths. Spread through air spaces (STAS) is an adverse prognostic factor that has become increasingly known in recent years. This study aims to investigate the impact of STAS presence on overall survival (OS) and disease-free survival (DFS) in patients with surgically resected stage IA-IIIA lung cancer and to identify clinicopathological features associated with STAS. Materials and Methods: This research involved 311 lung cancer surgery patients. The relationship between the presence of STAS in the patients' surgical pathology and OS and DFS values was examined. Clinicopathological features associated with the presence of STAS were determined. Results: There were 103 (33%) STAS-positive patients. Adenocarcinoma histological subtype, perineural invasion (PNI), and lymphovascular invasion (LVI) were significantly correlated with being STAS positive. STAS significantly predicted DFS and OS. One-year and five-year DFS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (65% vs. 88%, 29% vs. 62%, respectively, p ≤ 0.001). Similarly, one-year and five-year OS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (92% vs. 94%, 54% vs. 88%, respectively, p ≤ 0.001). In multivariate analysis, STAS was found to be an independent prognostic factor for both DFS and OS (HR: 3.2 (95%CI: 2.1-4.8) and 3.1 (95%CI: 1.7-5.5), p < 0.001 and <0.001, respectively). Conclusions: In our study, STAS was found to be an independent prognostic biomarker in operated stage IA-IIIA lung cancer patients. It may be a beneficial pathological biomarker in predicting the survival of patients and managing their treatments.

INTRODUCTION: Testicular germ cell tumors (seminoma/non-seminoma) are the most common carcinomas in young males, comprising approximately 1% of all carcinomas. In stage-I disease, orchiectomy can cure approximately 85% of patients. Post-surgical options are adjuvant therapy and active surveillance. Our study examined the effects of management options on stage-I seminoma patients followed in our center. METHODS: We evaluated the patients with stage-I testicular seminoma who underwent radical orchiectomy and followed up in the oncology center between 2001 and 2022. The outcomes of management options, survivals were retrospectively analyzed. The prognostic significance of risk factors for relapse on survival was evaluated. RESULTS: Of the 140 patients with stage-I seminoma, 49 (35%) were treated with adjuvant therapy, and 91 (65%) underwent surveillance. The median follow-up duration was 37 months. During the follow-up period, nine patients in the active surveillance group and four in the adjuvant therapy group had a recurrence. There was no statistically significant difference between the two groups (p = 0.67). In the surveillance group, the univariate and multivariate analyzes identified the presence of lymphovascular invasion (p = 0.005, HR: 0.13) as significant prognostic factor for disease-free survival (DFS). In the surveillance cohort, the 5-year DFS rate was 60% for patients with lymphovascular invasion and 93% for those without. There was statistical significance between the two groups (p = 0.003). CONCLUSION: Our study shows that adjuvant therapy does not significantly improve DFS compared to surveillance in patients. In addition, it has been shown that lymphovascular invasion is an important prognostic indicator for DFS in determining the treatment strategy.

Sarcomatoid renal cell carcinoma (sRCC) is a rare variant of renal cell carcinoma (RCC) and is associated with a poor prognosis. We reviewed the outcomes of patients from oncology centers in Turkey. Our aim is to share our real-life experience and to contribute to the literature. The demographic and clinical features, treatment, and survival outcomes of 148 patients with sRCC were analyzed. The median age at the time of diagnosis was 58 years (range: 19-83 years). Most patients (62.8%) had clear-cell histology. Most patients were in the intermediate Memorial Sloan-Kettering Cancer Center (MSKCC) risk group (67.6%) and were stage 4 at the time of diagnosis (63.5%). The most common sites of metastasis were the lung (60.1%), lymph nodes (47.3%), and bone (35.8%). The patients received a median of two lines (range: 0-6) of treatment. The most common side effects were fatigue, hematological side effects, hypertension, and hypothyroidism. The median follow-up was 20.9 months (range: 1-162 months). The median overall survival (OS) was 30.8 months (95% confidence interval: 24.9-36.7 months). In multivariate analysis, high MSKCC scores, sarcomatoid differentiation rates >50%, having stage 4 disease, and having lung metastasis at the time of diagnosis were independent factors for poor prognosis affecting OS. No difference was observed between patients who received tyrosine kinase inhibitor (TKI) as the first or second-line treatments. Similarly, no difference between TKI and immunotherapy as the second-line treatment. In conclusion, sRCC is a rare variant of RCC with a poor prognosis and response to treatment. Larger-scale prospective studies are needed to define an optimal treatment approach for longer survival in this aggressive variant.

This study aims to evaluate whether sarcopenia, measured by chest computed tomography (CT), affects survival outcomes and postoperative complications in soft tissue sarcoma (STS) patients undergoing surgery. In this retrospective study, CT scans of 79 patients were reviewed to measure pectoralis and T12 vertebra muscle area. Both were then adjusted for height (cm2/m2) as pectoralis muscle index (PMI) and T12 vertebra muscle index (TMI). Analyses were performed by dichotomizing muscle indices at gender-specific 50th percentile; PMI and TMI < 50th percentile were defined as low, and ≥50th percentile as high. Overall postsurgical complication rate (PCR) was 16%. Median length of hospital stay (LOHS) was 10 days (3-90). PMI and TMI were significantly lower in women (p = 0.02, p = 0.04). Median body mass index was significantly higher in high PMI and TMI groups (p = 0.01 for both). PCR and LOHS were similar between low and high PMI and TMI groups. Median follow-up was 29 months, 37 patients had recurrence and 23 died. No significant difference was noted between low and high PMI and TMI groups, in terms of disease-free or overall survival. PMI and TMI as measured by chest CT had no impact on survival outcomes or postoperative complications in localized STS.

Objective: The aim of this study was to investigate quality-of-life (QoL) in breast cancer (BC) patients treated with adjuvant endocrine therapy (AET). Methods: We designed a cross-sectional study of 233 BC patients treated with AET and used the Functional Assessment of Cancer Therapy - Breast questionnaire. Results: No significant difference was observed between endocrine agents. Duration of AET did not affect QoL. In the entire cohort, multivariate analysis determined age (p = 0.034) and switching treatment from tamoxifen to aromatase inhibitors (p = 0.049) as significant positive coefficients of QoL, while comorbidity (p = 0.072) tended to be associated with lower scores. Education level (p = 0.001) and chemotherapy (p = 0.04) were significant predictors of QoL in the tamoxifen group, while comorbidity (p = 0.04), surgery type (p = 0.02), radiotherapy (p = 0.006) and stage (p = 0.009) had a significant impact on QoL in aromatase inhibitors group. Conclusion: Evaluating the well-being of BC patients by QoL questionnaires is of great importance to identify particular subgroups that may require supportive care.
Breast cancer (BC) remains the most common cancer among women worldwide. Hormone receptor-positive (estrogen receptor- and/or progesterone receptor-positive) BC represents 70% of all cases. Advances in the treatment of disease lead to improved patient survival. As a result, quality-of-life (QoL) becomes a major concern in clinical practice. This study aimed to assess the impact of socio-demographic, clinical and treatment-related factors on QoL among patients with BC treated with adjuvant endocrine therapy. We used the Functional Assessment of Cancer Therapy Breast questionnaire to evaluate QoL. In the entire cohort, multivariate analysis determined age and switching treatment from tamoxifen to aromatase inhibitors to be significant positive coefficients of QoL, while comorbidity tended to be associated with lower scores. Education level and chemotherapy were significant determinants of QoL in the tamoxifen group, while comorbidity, surgery type, radiotherapy and disease stage had a significant impact on QoL in the aromatase inhibitor group. These findings can be utilized to identify certain subgroups that may need greater supportive care.

OBJECTIVE: To compare seroconversion for SARS-CoV-2 receptor-binding domain (RBD) specific IgG positivity against two doses of the CoronaVac vaccine in breast and lung cancer patients receiving systemic therapy, to determine the factors affecting seropositivity, and to observe long-term results up to a secondary booster vaccine. RESULTS: The analysis included 201 cancer patients (99 breasts, 102 lungs; median age: 59 years (range: 28-92), 42.3 % men) and 97 controls (median age: 62 years (range: 24-87), 38.1 % men). The seropositivity rate for RBD IgG after 2 doses of vaccine in the cancer group was 81.6 % (n=164) and 93.8 % (n=91) in the control group (p=0.005). The median IgG titer of cancer patients was significantly lower than in the control group (338 (IQR, 95-933) AU/mL vs 676 (IQR, 389-1270) AU/mL; p<0.001). Multivariate analysis of all the patients determined that having cancer (OR: 0.303, 95%CI: 0.123-0.750, p=0.010) and being over 60 years of age (OR: 0.447, 95%CI: 0.218-0.917, p=0.028) was associated with a reduced vaccine response. A subgroup analysis of cancer patients revealed that seroconversion was lower in men than in women (75.3 % vs 86.2 %, p=0.049) and lower in ≥60 patients than in <60 patients (75.9 % vs 89.4 %, p=0.014). DISCUSSION AND CONCLUSION: Cancer patients receiving an active systemic therapy with two doses of the CoronaVac vaccine had a lower antibody response than the non-cancer population, and deaths due to COVID-19 may occur in these patients despite the vaccine. Therefore, extensive protective measures should be taken to protect against COVID-19 in cancer patients aged 60 years and older, who have received two doses of the CoronaVac vaccine (Tab. 4, Fig. 4, Ref. 27).

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.

AIM: The aim of this study is to evaluate the efficacy and toxicity of trastuzumab emtansine (T-DM1) in cases with metastatic breast cancer (mBC) in different lines of treatment. METHOD: Retrospective analysis of T-DM1 results of human epidermal growth factor receptor 2 (Her2) positive 414 cases with mBC from 31 centers in Turkey. FINDINGS: Except 2, all of the cases were female with a median age of 47. T-DM1 had been used as second-line therapy in 37.7% of the cases and the median number of T-DM1 cycles was 9. Progression-free survival (PFS) and overall survival (OS) times were different according to the line of treatment. The median OS was found as 43, 41, 46, 23 and 17 months for 1st, 2nd, 3rd, 4th and 5th line, respectively (p = 0.032) while the median PFS was found as 37, 12, 8, 8 and 8 months, respectively (p = 0.0001). Treatment was well tolerated by the patients. The most common grade 3-4 adverse effects were thrombocytopenia (2.7%) and increased serum gamma-glutamyl transferase (2%). DISCUSSION: The best of our knowledge this is the largest real-life experience about the safety and efficacy of T-DM1 use in cases with mBC after progression of Her2 targeted treatment. This study suggests and supports that T-DM1 is more effective in earlier lines of treatment and is a reliable option for mBC.

Background: Gastric carcinoma (GC) patients usually present with locally advanced or metastatic disease; therefore treatment aim is mainly palliation. In this study our purpose is to analyze the prognostic values of the sarcopenia index (SI), cachexia index (CIn) and other inflammatory indexes (advanced lung cancer inflammation index [ALI], modified Glasgow Prognostic Score [mGPS], prognostic index [PI], prognostic nutritional index [PNI] and neutrophil-to-lymphocyte ratio [NLR]) in metastatic GC patients.Methods: Data from the files of metastatic GC patients, who applied to Medical Oncology outpatient clinic in Marmara University Pendik Education and Research Hospital between January 2011 and June 2016, were retrospectively reviewed. Five hundred seventy patients with gastric cancer were detected. Exclusion criteria were the inability to reach the patient surveys for prognostic index calculations, the presence of additional comorbidities to affect the laboratory parameters, and the absence of metastatic disease. Finally, 87 of these patients were included in this study. For SI calculation L3 level muscle area was measured from patients' computed tomography (CT) by a radiologist. SI reference value was obtained from western-EGWSOP (The European Working Group on Sarcopenia in Older People) and eastern (Harada Y, et al.) sources separately, as Turkey doesn't have a reference value for SI. NLR cutoff value was accepted as the median value of patients' NLR measurements. Statistical analysis was conducted using SPSS. Kaplan-Meier and Cox regression models were used to assess independent prognostic factors. The area under the curve was used to compare the prognostic value of indexes.Results: The median length of follow-up of 87 patients was nine months (1-64 mo,/s), and 78 patients died during follow-up. Fifty-nine patients were male (63%), and the median age was 62 (range, 23-88). According to univariate analysis high mGPS and PI score, PNI level <45, NLR level ≥ 3.41, ALI level <18, CI level under 35, SI (Harada Y, et al) ≤44.5 for males and ≤36.5 for females, ECOG score ≥ 2, weight loss more than 10% during last 6 mo, BMI under 24 were poor prognostic factors. Age, gender, having multiple organ metastasis, history of gastric surgery, positivity C-erb-B2, SI (EGWSOP) ≤52.4 for males, and ≤38.4 for females did not have any impact on survival. According to multivariate analysis, high mGPS (score 2) (HR 2,494, 95% CI 1.25-4 .94, p = 0.02), PNI (score 1) (HR 4.2, 95% CI 1.73-10.1, p < 0.001) and ECOG score (≥2) (HR 1.541, 95% CI 1,089-4,214, p = 0.004) have been found to be independent prognostic factors which are determining the survival. mGPS was found to be more valuable than other indexes for predicting mortality by measuring the AUC with ROC analysis.Conclusions: In our study, mGPS, PNI and ECOG score were independent indicators for shorter survival in metastatic gastric cancer patients. mGPS and PNI, which can be done by using only serum CRP, albumin level and complete blood count, might be inexpensive, practical and beneficial to use in routine clinical practice to determine survival.

PURPOSE: Malignant high-grade gliomas are the most common and aggressive type of primary brain tumor, and the prognosis is generally extremely poor. In this retrospective study, we analyzed the outcome of systemic treatment in recurrent high-grade glioma patients and the impact of prognostic factors on survivals. METHODS: Data from 114 patients with recurrent high-grade glioma who received systemic treatment and followed in our clinic between 2012 and 2018 were retrospectively analyzed. Eastern Cooperative Oncology Group (ECOG) performance status, age, gender, histology, type of surgical resection, side effects after systemic treatment (deep vein thrombosis, hypertension, proteinuria), IDH1 and alpha thalassemia/mental retardation syndrome X-linked (ATRX) mutation status were investigated as prognostic factors for progression-free survival and overall survival. RESULTS: At the time of diagnosis, the median age was 48 (17-77) and 68% of the patients were male. Most common pathologic subtype was glioblastoma multiforme (68%). Median follow-up duration was 9.1 months (1-68 months). Median progression-free survival and overall survival were 6.2 months and 8 months, respectively. In multivariate analysis, ECOG PS, deep venous thrombosis and the presence of ATRX and IDH1 mutation were found to be independent prognostic factors for progression-free survival (p < 0.05) and, ECOG PS, the presence of ATRX and IDH1 mutation for overall survival (p < 0.05). CONCLUSION: Our study is real life data and the median progression-free survival and overall survival rates are similar to the literature. We have found ECOG PS, presence of ATRX and IDH1 mutation to be independent prognostic factors for both progression-free survival and overall survival.

PURPOSE: The optimal chemotherapy regimen for concurrent chemoradiation in locally advanced non-small cell lung cancer (NSCLC) remains unclear. Cisplatin-etoposide regimen related toxicity is high, weekly regimens have been investigating. We aimed to compare the efficacy and safety of different concurrent chemotherapy regimens in the context. METHODS: A total of 225 patients with locally advanced, unresectable stage III NSCLC were included. Patients who were treated with weekly docetaxel-platin (DP), paclitaxel-platin (PP) and standard dose etoposide-platin (EP) chemotherapy regimens were selected and divided into groups for the comparison of toxicity, response rate, progression free survival (PFS), and overall survival (OS) times. RESULTS: There was a statistically significant difference between overall response rate of each treatment groups (DP: 96.1%, PP: 94% and EP: 76.7%, p < 0.001). The median PFS time of patients who were treated with DP, PP and EP was 16, 15 and 13.3 months, respectively (p = 0.435). The median OS time of patients treated with DP, PP and EP was 19.2, 29.7 and 28.3 months, respectively (p < 0.001). The rates of adverse events such as nausea, vomiting, neuropathy and anaphylaxis was similar. Grade 1-2 mucositis or esophagitis, anemia, pneumonitis were significantly higher in PP group than other groups. However, hematologic toxicities were higher in the EP group than other groups. CONCLUSIONS: Compared to the weekly chemotherapy regimens with the standard dose, our study demonstrated similar PFS, but a prolonged OS with the EP regimen. The clinical response rate of weekly regimens was better than the full-dose regimen. Adverse events and toxicity rates were different and depended on the type of chemotherapy regimen used.

OBJECTIVE: Fear of cancer recurrence (FCR) is an important psychological trauma associated with reduction in the quality of life, disruptions in the level of adjustment, emotional distress and anxiety. The purpose of the study was to evaluate the impact of patient-physician relationship on FCR. METHODS: The study was designed as a multicentre survey study. The cancer survivors, who were under remission, were evaluated with structured questionnaires. Patient-physician relationship (PPR) scale in which higher scores indicate better relationship and FCR inventory was used. RESULTS: Between January and April 2019, 1,580 patients were evaluated. The median age was 57.0 (19-88), and 66% were female. There was high level of FCR scores in 51% of participants. There was a negative correlation between PPR and FCR scores (r = -.134, p < .001). In multivariate analysis, young age, female gender, history of metastasectomy and worse PPR were associated with high levels of FCR. CONCLUSION: It is the first data showing the adverse impact of worse PPR on FCR. The strategies to improve the PPR should be practised. In addition, the cancer survivors, who are under the risk of FCR, should be evaluated and managed.

INTRODUCTION: Inflammatory myofibroblastic tumor is a rare disease which is typically seen in children and young adults. Approximately half of the inflammatory myofibroblastic tumors contain translocations that result in over-expression of anaplastic lymphoma kinase gene. Herein, we present two anaplastic lymphoma kinase-positive cases with long-term remission with crizotinib. We do not know how long these therapies need to be continued. CASE REPORTS: We present two cases of inflammatory myofibroblastic tumor treated with anaplastic lymphoma kinase inhibitor therapies: an 8-year-old Turkish boy and a 21-year-old Caucasian man. MANAGEMENT AND OUTCOME: Two cases, both with good tumor control under crizotinib, but one who progressed on drug holiday, responded again to the same drug, and had a very short period of response after restarting crizotinib. CONCLUSION: A molecular-targeted drug (anaplastic lymphoma kinase inhibitor) was found to be extremely effective as selective therapy for inflammatory myofibroblastic tumor with anaplastic lymphoma kinase translocation. Here, we want to emphasize the continuation of this treatment after achieving a good response until progression or a major side effect.

BACKGROUND: Anti-angiogenic tyrosine kinase inhibitors, sunitinib and pazopanib, have proven efficacy in advanced renal cell carcinoma, with specific adverse events occurring during treatment process. Comorbidities can reflect functional status and have prognostic value in oncology patients. We aimed to assess the association of the Charlson Comorbidity Index with severe toxicities and mortality in renal cell carcinoma cases treated with front-line sunitinib or pazopanib. METHODS: Files of locally advanced and metastatic renal cell carcinoma patients who received first-line sunitinib or pazopanib were retrospectively examined. Charlson Comorbidity Index of each patient was calculated. Patients were also stratified into Memorial Sloan-Kettering Cancer Center risk groups. Predictors of dose-limiting toxicity were evaluated with binomial logistic regression analysis. Univariate and multivariate Cox regression models were utilized to determine prognostic factors for survival. RESULTS: The study included 102 patients, 64 were treated with first-line sunitinib and 38 with pazopanib. In 42 patients (41.9%), Charlson Comorbidity Index was 9 or more. Dose-limiting toxicities were significantly more frequent in Charlson Comorbidity Index ≥9 group (69% vs. 40%, p = 0.004), and Charlson Comorbidity Index independently predicted dose-limiting toxicity (Hazard ratio (HR) = 4.30, p = 0.002). After adjusting for other variables, a Charlson Comorbidity Index of ≥9 is also a significant prognostic factor for progression-free (HR = 1.76, p = 0.02) and overall survival (HR = 1.75, p = 0.03). CONCLUSIONS: Charlson Comorbidity Index may be a valuable method to estimate prognosis and optimize therapy in patients with advanced renal cell carcinoma receiving first-line sunitinib or pazopanib.

INTRODUCTION: Primary choriocarcinoma of the colon is an extremely rare neoplasm which has a poor prognosis. Only 18 cases have been previously reported in English medical literature. Here we present a case of primary rectal choriocarcinoma with a good response to chemotherapy and review the literature on this uncommon tumor. CASE REPORT: A 36-year-old woman presented with abdominal pain and vaginal bleeding. Abdominal magnetic resonance imaging revealed 6.9 × 5.3 × 6.4 cm hypervascular mass posterior to uterus very close to rectum. Beta-human chorionic gonadotropin (ß-hCG) level was markedly elevated. Low anterior resection of the rectum with lymph node dissection and total abdominal hysterectomy with bilateral salpingo-oophorectomy were performed. Pathologic diagnosis was reported as colonic choriocarcinoma with a focal component of adenocarcinoma. Post-operative magnetic resonance imaging detected multiple metastatic lesions throughout the liver. The patient was treated with systemic chemotherapy using bleomycin, etoposide and cisplatin (BEP protocol). After three cycles, ß-hCG level decreased to normal and magnetic resonance imaging showed regression of liver metastasis. However, the patient died of respiratory failure due to bleomycin toxicity and pneumonia accompanied by rapid disease progression. DISCUSSION: This is an extremely rare case of primary rectal choriocarcinoma. Due to poor prognosis of the disease, it seems very important to start prompt treatment to improve patient's survival.

PURPOSE: Neoadjuvant chemotherapy is the standard front-line treatment modality in locally advanced breast cancer. Achieving pathological complete response (pCR) is a significant prognostic factor for prolonged disease-free and overall survival. Insulin resistance is defined as a pathological condition in which insulin effect is impaired in peripheral target tissues such as the skeletal muscle, liver, and adipose tissue. The relationship between breast cancer and insulin resistance is controversial. In this study, our aim is to evaluate the role of insulin resistance, body mass index (BMI), metabolic syndrome, and inflammation markers to predict complete response in breast cancer patients who underwent neoadjuvant treatment. METHODS: Data from 55 locally advanced non-diabetic breast cancer patients, treated with neoadjuvant chemotherapy between 2015 and 2017, were retrospectively evaluated. Homeostatic model assessment, IR = insulin resistance (HOMA-IR) was calculated by using the obtained insulin and fasting blood glucose values before neoadjuvant chemotherapy (fasting insulin × fasting glucose/405). We considered a cut-off of 2.5 for insulin resistance. The systemic inflammatory index (SII), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were calculated. RESULTS: Twenty-five patients had no insulin resistance. The most common pathologic subtype (56%) was hormone receptor (HR) positive and human epidermal growth factor receptor-2 (Her-2)-negative invasive ductal carcinoma. Sixteen (29%) patients had a pathological complete response (pCR). We found that the probability of pCR in patients with insulin resistance was 4.7 times lower than that in patients without insulin resistance [OR: 4.7 (95%CI 1.7-17.2), p = 0.01]. CONCLUSION: Our results revealed that insulin resistance may have a negative effect on pathological complete response (pCR) following neoadjuvant therapy particularly with hormone-positive and Her-2-negative cases of non-diabetic breast cancer.

BACKGROUND: Rectum cancer is a type of colorectal cancer. Its etiology and etiopathogenesis are similar to other colon diseases. We aimed to evaluate the tumor budding for predicting prognosis of resected rectum cancer patients. METHODS: We retrospectively collected the data of 75 operated rectum adenocarcinoma patients who were treated neoadjuvant chemoradiotherapy between 2013 and 2018 in Umraniye Research and Training Hospital and Acibadem University Medical Oncology Outpatient Clinic. Tumor budding was investigated as a prognostic factor for disease-free survival. RESULTS: This study included 75 rectum cancer patients and 51 were male (68%). Median age was 56 (range 19 to 77 years). There were 29 (39%) and 46 (61%) patients in tumor budding low-intermediate and high groups respectively. In multivariate analysis, tumor budding was found to be an independent prognostic factor for disease-free survival (p = 0.00). CONCLUSIONS: According to our study, having high tumor budding suggests a high likelihood of relapse. Therefore, we might need additional follow-up protocol in these patients.
