RESUMO
INTRODUCTION: Male breast cancer, comprising approximately 1% of all breast cancer cases, often leads to the exclusion of male patients as a criterion in clinical trials. While the efficacy of Cyclin-dependent kinases 4 and 6 (CDK 4/6) inhibitors has been established in metastatic hormone receptor-positive (HR +) and human epidermal growth factor receptor 2-negative (HER2 -) breast cancer in women, limited data exist on their effectiveness in male patients. We aimed to evaluate the efficacy and safety of palbociclib or ribociclib in male patients with breast cancer. METHODS: This study is a multicenter, retrospective study. We included male patients with HR + and HER2-metastatic breast cancer who received palbociclib or ribociclib as first-line treatment. Our primary endpoints were progression-free survival (PFS), overall response rates (ORR), and drug-related adverse effects. RESULTS: A total of 46 male patients from 27 institutions were enrolled. The median age at initiation of CDK 4/6 inhibitors was 63.64 ± 13.69 years, with a median follow-up of 21.33 (95% CI 14.92-27.74) months. The ORR were 84% for palbociclib and 76.2% for ribociclib. The mPFS for the entire cohort was 28.06 months (95% CI 18.70-37.42). No significant difference in PFS was observed between palbociclib and ribociclib (mPFS: 24.46 months (95% CI 11.51-37.42) vs 28.33 months (95% CI 14.77-41.88), respectively, p = 0.211). No new adverse events were reported. DISCUSSION: This study demonstrates that palbociclib and ribociclib are effective and safe options for first-line treatment in male patients with HR + /HER2 - metastatic breast cancer. However, further prospective studies are warranted to establish their efficacy in this population.

BACKGROUND: There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). METHODS: A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and ≥ 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. RESULTS: The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. CONCLUSION: Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET.

PURPOSE: This study analyzed the late ear complications of radiotherapy for nasopharyngeal cancer (NPC) and compared the conventional and intensity-modulated radiotherapy (2D-RT and IMRT, respectively). METHODS: At 2-21 years after the end of NPC treatment, 104 ears of 52 patients were evaluated with the otoscopic examination, pure tone audiometry test, tympanometry, and subjective complaints by being blinded to the radiotherapy technique. RESULTS: There were no differences in terms of the pathology of the external, middle or inner ear, air and bone-conduction hearing thresholds, and the air-bone (A-B) gap at 500, 1000, 2000, and 4000 Hz, and tympanometry types between 2D-RT and IMRT groups (p > 0.05). There were positive correlations between the values of A500 and A1000 thresholds; gap 500, 4000, and mean cochlear RT dose (p < 0.05). There were positive correlations between the values of A500, A1000, and A4000 thresholds; gap 500, 1000, 2000, 4000, and maximum cochlear RT dose (p < 0.05). CONCLUSION: IMRT was not found to be superior to 2D-RT to prevent RT-induced ear complications. The solution of the middle ear problems must be the goal of the strategies for complications treatment.

While some clinics have adopted abbreviated neoadjuvant treatment for HER2-positive breast cancer, there remains a shortage of comprehensive clinical data to support this practice. This is a retrospective, multicenter study. A total of 142 patients were included in the study who are HER2-positive breast cancer, aged ≤ 65 years, with left ventricular ejection fraction ≥ 50%, received neoadjuvant chemotherapy and underwent surgery at 10 different oncology centers in Türkiye between October 2016 and December 2022. The treatment arms were divided into 4-6 cycles of docetaxel/trastuzumab/pertuzumab for arm A, 4 cycles of adriamycin/cyclophosphamide followed by 4 cycles of taxane/TP for arm B. There were 50 patients (35.2%) in arm A and 92 patients (64.8%) in arm B. The median follow-up of all of the patients was 19.9 months (95% CI 17.5-22.3). The 3-year DFS rates for treatment arms A and B were 90.0% and 83.8%, respectively, and the survival outcomes between the groups were similar (p = 0.34). Furthermore, the pathologic complete response rates were similar in both treatment arms, at 50.0% and 51.1%, respectively (p = 0.90). This study supports shortened neoadjuvant treatment of HER2-positive breast cancer, a common practice in some clinics.

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.
RESUMO
Introduction Our aim in this study is to examine the clinical features of gallbladder polyps (GBPs) detected by preoperative ultrasonography (USG) or after cholecystectomy, especially benign and malignancy. Methods One thousand seven hundred patients between the ages of 18-80 who were operated on for cholecystectomy between January 1, 2015, and January 1, 2020, in Ankara Batikent Medicalpark hospital were evaluated in this study. Of these patients, 149 patients who were operated on due to polyp detected in USG, who were accompanied by polyp while being operated on for another reason, or who had a benign or malignant polypoid structure in postoperative pathology were examined. Mann-Whitney U test was used for continuous variables and the chi-square test was used for categorical variables. Results The mean age for patients with polyps was 44.6 years (range: 21-78). When the patient distribution was evaluated according to gender, although women were more, they were proportionally close to each other (female 77 (51.7%), male 72 (48.3%)). When the polyps were examined in pathology, 20 (13.4%) patients did not have polyps. Given the other patients, hyperplastic polyps were detected in 15 (10.1%), cholesterol polyps in 104 (69.8%), and adenocarcinomas in five (3.4%) of them. Of the patients with adenocarcinoma, two had T2 and three had T1 tumors. Two of the patients with gallbladder cancer had sessile polyps below 5 mm. Of the malignant cases, four were female and one was male. The median age in malignant cases was 55 years. All malignant cases had single polyps. Conclusion In conclusion, in our study, it was observed that most postoperative GBPs were benign - malignancy should come to mind at an advanced age - and was compatible with current malignant polyp risk factors. Contrary to the literature, female gender dominance was present in our malignant cases.
RESUMO
AIMS AND OBJECTIVES: To examine the impact of the workforce crisis on healthcare service delivery for a year during the coronavirus disease 2019 (COVID-19) pandemic on healthcare service delivery and hospital economy in a healthcare facility. MATERIALS AND METHODS: An examination was conducted of employees who were issued with a report for incapacity to work due to the pandemic between March 2020 and March 2021. A record was made of the employees' ages, genders, fields of work and lost workdays. The employees were classified as physicians, nursing services, guest services, hotel services, and support services. Diagnoses were made of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), based on computed tomography (CT) and polymerase chain reaction (PCR) test results. Employees diagnosed with SARS-CoV-2 infection were put into isolation in the hospital during the first months of the pandemic, and treatment was initiated in accordance with the protocols. By contrast, during the last eight months, our personnel who were not indicated for hospitalization completed their treatment in a home isolation setting. According to the Turkish Ministry of Health COVID-19 (SARS-CoV-2 Infection) Scientific Advisory Board Study Guide, the isolation period was initially 14 days, before being reduced to 7-10 days, in line with the revised guide. Employees with at least one negative PCR test result following isolation were allowed to return to work. RESULTS: The study included 575 individuals who were employed at our hospital between March 2020, when the first case was identified in Turkey, and March 2021. Among these employees, 257 were issued with a report for incapacity to work due to COVID-19. Of these, 239 had a positive PCR test result. There were 11 individuals who just had symptoms and/or positive CT findings but a negative PCR test result. There were only seven individuals who were put into isolation due to high-risk contact. The combined lost workdays of the employees totaled 3792. The highest lost workday rate (52%) was in nursing services (1973 days, n = 126). There was no mortality. Conclusion: Lost workdays due to the pandemic in the midsize healthcare facility severely affected the morale and motivation of both the diagnosed and the remaining employees. Hospital administrations also had difficulties in maintaining the quality and continuity of the services provided.
RESUMO
In glioblastoma multiforme (GBM) cases, the tumor usually remains limited to the central nervous system in the expected disease course. Here, we discuss the case of a 41-year-old male patient who presented with extracranial spread, which has been reported in a limited number of cases in the literature. The patient received six lines of treatment including radiotherapy with temozolomide, irinotecan-bevacizumab combination, lomustine, erlotinib, everolimus, and weekly carboplatin-paclitaxel. In addition to systemic treatment, the patient underwent radiotherapy and surgery twice. Despite presenting with features consistent with a poor prognosis and extensive multi-organ metastasis, the patient achieved an overall survival of 25 months. In our view, the clinical course of our case, the follow-up, and the treatment process will add to the literature.
RESUMO
Cystic lymphangioma presenting with multiple bone lesions in an adult patient is a rare occurrence, with a limited number of reported cases in the literature. In this case report, we describe a 32-year old female patient with chronic neck and pelvic pain, and multiple lytic bone lesions on radiological imaging, which were eventually discovered to originate from cystic hygroma and widespread bone lymphangiomas that were present for more than 10 years. It should be kept in mind that there may be multiple benign causes of differential diagnosis in patients presenting with findings suggestive of diffuse bone metastasis. Misdiagnosis may cause the patient to receive unnecessary treatments, especially radiotherapy. In this case, we reached the diagnosis of benign disease, diffuse bone lymphangiomatosis. For this purpose, we also examine the long and stable medical history of the patient with the findings of BT, ultrasound, and bone scintigraphy. We think that as long as there are no stable and serious results ofclinical and radiological findings of the patient, the patient should be approached with medical follow-up without treatment.

OBJECTIVE: We aimed to investigate the roles of inflammatory parameters, including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), and C-reactive protein/albumin ratio (CAR), in predicting disease recurrence in patients with stage IIA (T3N0M0) high microsatellite instability and microsatellite-stable colon cancer who had no risk factors associated with relapse. MATERIALS AND METHODS: We evaluated 155 patients with colon cancer followed in 3 hospitals in Turkey between February 2009 and March 2020. These patients had stage IIA disease and had no risk factors associated with relapse. None of the patients received adjuvant chemotherapy. NLR, PLR, LMR, and CAR parameters were retrospectively obtained from laboratory results at the time of diagnosis, and their associations with disease recurrence were assessed. RESULTS: Over a median follow-up period of 38 months (range: 4-98 months), 11 of the 155 patients experienced relapse or developed metastases. Multivariate Cox analyses revealed that NLRs of ≥3.12 (hazard ratio [HR]: 0.041, 95% confidence interval [CI]: 0.048-0.826, p = 0.006) and CARs of ≥0.027 (HR: 0.199, 95% CI: 0.004-0.404, p = 0.026) were independent prognostic markers predicting relapse. The median 5-year recurrence-free survival rate of patients with NLRs of ≥3.12 at the time of diagnosis was 88.0%; this rate was 100% in patients with NLRs of <3.12 (p < 0.001). Similarly, the median 5-year recurrence-free survival rate of patients with CARs of ≥0.027 at the time of diagnosis was 84.7%; this rate was 95.7% in patients with CARs of <0.027 (p = 0.016). CONCLUSION: In this study, NLR and CAR were found to be independent prognostic markers predicting disease recurrence in patients with stage IIA colon cancer who did not receive adjuvant chemotherapy due to low clinical risk.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare but highly aggressive neuroendocrine carcinoma of the skin. In this study, we aimed to evaluate the clinicopathologic characteristics, treatment outcomes, and survival of MCC cases in Turkey. MATERIALS AND METHODS: The patients diagnosed with MCC between 1999 and 2018 at twenty different centers in Turkey were included in the study. Patient and tumor characteristics and adjuvant and metastatis treatment outcomes were analyzed retrospectively. RESULTS: The median age of totally 89 patients was 70 (26-93). The most common primary location was lower limbs (n = 29, 32.5%). Immunohistochemically, CK20 positivity was present in 59 patients (66.3%). Only two patients had secondary malignancy. The majority of the patients (n = 76, 85.4%) were diagnosed at the localized stage. Surgery was performed for all patients in the early stage, and adjuvant radiotherapy or/and chemotherapy was applied to 52.6% (n = 40) of nonmetastatic patients. The median follow-up was 29 months. Recurrence developed in 21 (27.6%) of the 76 patients who presented with local or regional disease. Two-year disease-free survival (DFS) was 68.1% and 5-year DFS was 62.0% for localized stage. The 5-year DFS was similar for patients receiving adjuvant treatment (chemotherapy, radiotherapy, or sequential chemoradiotherapy) and without adjuvant therapy (P > 0.05). Two-year overall survival in patients who presented with localized disease was 71.3% and 18.5% in metastatic patients (P < 0.001). In the metastatic stage, platinum/etoposide combination was the most preferred combination regimen. Median progression-free survival (PFS) in first-line chemotherapy was 7 months (95% confidence interval: 3.5-10.5 months; standart error: 1.78). CONCLUSIONS: Although MCC is rare in Turkey, the incidence is increasing. Gender, CK20 status, tumor size, lymph node involvement, and adjuvant treatment were not associated with recurrence.

PURPOSE: Germ cell tumors (GCTs) are rare and highly curable malignancies. However, salvage treatments for relapsed or refractory disease are needed in approximately 20-60% of the patients. As salvage therapy, autologous stem cell transplantation (ASCT) administered after high-dose chemotherapy (HDCT) may be a feasible option as well as standard dose chemotherapy (SDCT). This study aimed to evaluate the efficacy and toxicity of ASCT in salvage therapy of GCTs retrospectively. Materials and Methods: Male patients older than 18 years of age who underwent ASCT due to a relapsed/refractory GCT were included in the study. RESULTS: The median age of 18 patients included in the study was 28 (19-46). The majority of patients (n:16, 88.8%) had non-seminomatous GCT histology. All of the patients had relapsed or refractory GCTs and received bleomycin, etoposide, cisplatin (BEP) combination therapy previously. Half of the patients were in the poor risk group. ASCT was administered as a second-line therapy in 14 (77.7%) patients and third-line therapy in four (22.2%) patients. There is no ASCT-related exitus. Febrile neutropenia (FN) developed in almost all patients. Complete response (CR) was obtained in 7 (38.8%) patients, partial response (PR) in four (22.2%) patients after ASCT. The 2-year PFS was 44.4% and the median PFS was 8.7 (2.7-12.6) months. Median OS was 22.7 (3.9-41.7) months and 3 years OS was 50.0%. CONCLUSION: In conclusion, ASCT was found to be an effective and safe treatment option in salvage therapy of GCT patients in our study.
