RESUMEN

Aim: To compare the seropositivity rate of cancer patients with noncancer controls after inactive SARS-CoV-2 vaccination and evaluate the factors affecting seropositivity. Method: Spike IgG antibodies against SARS-CoV-2 were measured in blood samples of 776 cancer patients and 715 noncancer volunteers. An IgG level ≥50 AU/ml is accepted as seropositive. Results: The seropositivity rate was 85.2% in the patient group and 97.5% in the control group. The seropositivity rate and antibody levels were significantly lower in the patient group (p < 0.001). Age and chemotherapy were associated with lower seropositivity in cancer patients (p < 0.001). Conclusion: This study highlighted the efficacy and safety of the inactivated vaccine in cancer patients. Clinical Trials Registration: NCT04771559 (ClinicalTrials.gov).


Cancer patients are at high risk for infection with SARS-CoV-2 and of developing the associated disease, COVID-19, which therefore puts them in the priority group for vaccination. This study evaluated the efficacy and safety of inactive SARSCoV-2 vaccination, an inactivated virus vaccine, in cancer patients. The immune response rate, defined as seropositivity, was 85.2% in the cancer patient group and 97.5% in the control group. The levels of antibodies, which are blood markers of immune response to the vaccine, were also significantly lower in the patient group, especially in those older than 60 years and receiving chemotherapy. These results highlight the importance of determining the effective vaccine type and dose in cancer patients to protect them from COVID-19 without disrupting their cancer treatment.

RESUMEN

OBJECTIVES: This study examines the relationships between fear of cancer recurrence (FCR), spiritual well-being (SWB) and psychological resilience in breast cancer survivors during the COVID-19 outbreak, and investigates to what extent breast cancer survivors' sociodemographic characteristics affect FCR, SWB and psychological resilience levels. METHODS: The study was conducted at Canakkale University Hospital in Turkey. Included in the study were 82 non-metastatic breast cancer patients whose clinical outcomes were followed-up after primary treatment, but suspended due to the COVID-19 outbreak. FCR, SWB and psychological resilience were assessed using the FCR inventory-short form (FCRI-SF), SWB scale and the brief resilience scale (BRS), respectively. RESULTS: The mean scores of breast cancer survivors concerning FCR, SWB, and psychological resilience were 17.77 ± 5.38, 36.20 ± 6.21 and 20.01 ± 4.51, respectively. A significant negative correlation was noted between the scores of FCR and SWB and psychological resilience (r = -0.329, p < 0.001 and r = -0.316, p = 0.004, respectively). Additionally, a significantly positive correlation was identified between psychological resilience and SWB (r = 0.501, p = 0.003). A hierarchical linear regression analysis with FCRI-SF as the dependent variable, and SWB and BRS as explanatory variables, indicated that SWB affects FCRI-SF scores and is a potential predictor of FCR. A mediation analysis revealed that SWB partially mediated the relationship between psychological resilience and FCR. CONCLUSION: Breast cancer survivors with high SWB and psychological resilience scores experience less FCR, despite their failure to maintain the medical follow-up due to the COVID-19 outbreak. Efforts should be made to increase the psychological resilience and SWB of patients diagnosed with breast cancer.

RESUMEN

BACKGROUND: The present study evaluates the development of edema, the change in the AQP3, AQP4, p53 and Bax gene expressions, and the protective effects of melatonin in rat hearts administered with cisplatin. METHODS AND RESULTS: A total of 28 Wistar albino rats were divided into four groups. The vehicle was administered intraperitoneally (i.p.) to the rats in the control group. The melatonin group (Mel) received melatonin at a dose of 10 mg/kg for 13 days. The cisplatin group (Cis) received cisplatin on days 1, 5, 9 and 13 at a dose of 4 mg/kg. The rats in the cisplatin + melatonin (Cis+Mel) group underwent the procedures both in the Mel and Cis groups. Blood and left ventricular samples were taken and analyzed on day 14 of the study. AQP3, p53 and Bax gene expressions were found to be significantly increased following cisplatin administration compared to the control, while melatonin administration significantly decreased the expression of these genes (p < 0.05). Melatonin administration also significantly decreased the level of AQP4 gene expression compared to the cis. On histological examination, congestion, hemorrhage, extracellular and intracellular edema, and degenerative changes were significantly more common in the Cis than in the control. Melatonin administration significantly decreased intracellular edema (p = 0.010) and degenerative changes (p = 0.010), and the improvement in extracellular edema was close to statistical significance (p = 0.051) in melatonin. CONCLUSIONS: These results indicate that melatonin had an ameliorative effect on myocardial edema and AQP channels, and that it may be used as a protective molecule against myocardial edema secondary to cisplatin administration.

RESUMEN

PURPOSE: We aim to compare the efficiency and toxicity of three different 5-fluorouracil (5-FU) administration types in 5-FU, leucovorin, and oxaliplatin (FOLFOX) combination treatment for adjuvant therapy in colorectal cancer (CRC). METHODS: Five hundred and seventy patients with stage III colorectal carcinoma who received different FOLFOX regimens after curative resection were included. Patients were divided into three groups as FOLFOX-4, modified FOLFOX-6 (mFOLFOX-6), and mFOLFOX-4 for comparison of toxicity and disease-free survival (DFS) and overall survival (OS) times. RESULTS: Three-year DFS rates for FOLFOX-4, mFOLFOX-6, and mFOLFOX-4 groups were 65%, 72%, and 72%, respectively. Five-year OS rates for FOLFOX-4, mFOLFOX-6, and mFOLFOX-4 groups were 69%, 75%, and 67%, respectively. There was no statistically significant difference between the three treatment groups in terms of DFS and OS (p = 0.079, and p = 0.147, respectively). Among grade 1-2 adverse events (AE), thrombocytopenia, neuropathy, and stomatitis were more common in the mFOLFOX-6-treated group. The frequency of grade 1-2 nausea and vomiting were similar in mFOLFOX-6 (36.3% and 24%, respectively) and mFOLFOX-4 (32.4% and 24.7%, respectively) groups but were higher than that in the FOLFOX-4 (19.5% and 11.3%, respectively) group. Among the most common grade 3-4 AE, neutropenia (53.4%, 9%, and 13.5%, respectively) and diarrhea (10.5%, 2.2%, and 2.4, respectively) were more common in FOLFOX-4. The rate of anemia and febrile neutropenia was similar in treatment groups (p = 0.063, and p = 0.210, respectively). CONCLUSION: In the adjuvant treatment of stage III CRC patients, three different 5-FU administration types in FOLFOX combination treatment can be used with similar efficiency and manageable toxicity.

RESUMEN

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.

RESUMEN

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913-2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15-iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840-841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words "cancer" and "oncologist" meant for the students. The participant students were analyzed in two study groups; "group 1" (n = 1.255) were phases I and II students that had never attended an oncology lesson, and "group 2" (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of "death" (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students' understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country.

RESUMEN

Identification of biomarkers used for the prognostic evaluation of non-small cell lung cancer (NSCLC) patients is important. The aim of this study was to evaluate the potential prognostic value of XRCC1, ERCC1, ERCC2, and TP53 single nucleotide polymorphisms (SNPs) in completely resected NSCLC patients. In total, 130 patients, surgically treated for NSCLC between 2000 and 2012, were included. An analysis of SNPs from peripheral blood cells was performed by polymerase chain reaction. XRCC1 Arg399Gln, ERCC1 Asn118Asn, ERCC2 Lys751Gln, and TP53 Arg72Pro polymorphisms were evaluated in conjunction with clinical and pathological parameters and survival. Kaplan-Meier method and Cox regression analysis were used. Median age rate was 59.3, ranging between 36 and 78 years. Median relapse-free survival duration (RFS) was found as 46.2 months. In those with ERCC2 CC allele, median RFS was detected as 28.3 months (95 % confidence interval (CI), 20.8-35.8), 46.9 months in those with CT heterozygous (95 % CI, 18.6-75.2), and 80.1 months for those with TT mutant allel (95 % CI, 33.0-127.2). Median RFS was seen to be longer in mutant group and also statistically significant (P = 0.018). Additionally, upon evaluating CC normal group with CT + TT alleles including mutant alleles, median RFS was found as 56.5 months (95 % CI, 24.6-88.4) in CT + TT group, and this was statistically significant (P = 0.005) Also, median RFS was 15.1 months in those including ERCC2 CC allele and 56.5 months in CT + TT allele in the group with no adjuvant treatment (P = 0.001). In conclusion, our study showed that ERCC2/XPD polymorphism is an independent prognostic factor in operated NSCLC patients, and these findings should be supported with prospective studies.

RESUMEN

PURPOSE: Relatively few studies have focused on T4N2 (stage IIIB) locally advanced non-small cell lung cancer (NSCLC). In this study, we tried to identify prognostic factors for patients with clinical stage T4N2 NSCLC. METHODS: We retrospectively identified 223 patients, of which 168 met the inclusion criteria. Patients treated with curative intent using concurrent chemoradiotherapy (CRT) with or without adjuvant chemotherapy, or concurrent CRT after induction chemotherapy, were included in this study. Relevant patient, treatment, and disease factors were evaluated for their prognostic significance in both univariate and multivariate analyses using the Cox proportional hazards model. RESULTS: The median progression-free survival (PFS) was 13 months (95% confidence interval [CI], 10.6-15.4). The median overall survival (OS) was 20 months (95% CI, 16.8-23.1), and 71, 40.3 and 28.2% of the patients survived for 1, 2 and 3 years after diagnosis, respectively. Multivariate analysis showed Eastern Cooperative Oncology Group (ECOG) performance status (PS) was independent predictor of PFS (hazard ratio [HR], 0.24; 95% CI, 0.13-0.43; p=0.001), and OS [HR, 0.48; 95% CI, 0.26-0.87; p=0.015). Absence of multifocal T4 tumors was also associated with a significantly longer OS (HR, 046; 95% CI, 0.31-0.7; p=0.001). There was no statistically significant difference in OS and PFS between treatment modalities. CONCLUSION: PFS and OS were significantly shorter in patients with poor ECOG PS. OS was also significantly shorter in patients with multifocal T4 tumors. There were no differences between the two therapeutic approaches with respect to outcome.

RESUMEN

Presentation with bone marrow metastasis at diagnosis is a rare event in breast carcinoma. Here, we report a rare presentation of metastatic breast cancer patient with bone marrow metastases, who was successfully treated with trastuzumab combined chemotherapy. The regimens initially applied for bone marrow metastasis were docetaxel/adriamycin, gemcitabine/vinorelbine, epirubicin/cyclophosphamide, capecitabine, docetaxel, gemcitabine, and paclitaxel. But, the best response to these regimens was not satisfactory. Our patient was completely treated with etoposide-cisplatin and trastuzumab combination. She is still on remission after five years of metastatic breast cancer diagnosis using letrozole and trastuzumab without complication. Physicians should be careful in treating bone marrow metastases in breast cancer, since patients can show improved marrow function after chemotherapy and long-lasting survival is possible.

RESUMEN

Introduction: Crizotinib is a tyrosine kinase inhibitor used in patients with non-small cell lung cancer, and there are uncertainties about its effect on kidney function. In this study, it was aimed to document the possible adverse effect of the drug on kidney functions. Materials and Methods: The estimated glomerular filtration rates (eGFRs) of the patients were calculated by creatinine-based Chronic Kidney Disease Epidemiology Collaboration and compared by months using the paired samples t-test. Kaplan-Meier survival method was used for progression-free survival and overall survival (OS) analysis. Results: Twenty-six patients who received crizotinib were included in the study, and the median progression-free survival time with crizotinib was 14.2 months and the median OS time was 27.4 months. There was a significant reduction of eGFR after the 1st month of crizotinib treatment when compared to the rate before treatment initiation (P < 0.001). The eGFR values at the end of the 1st month and the 2nd month of treatment and the 2nd and 3rd months of treatment were statistically similar (P = 0.086, P = 0.663; respectively). This decrease in eGFR values was reversible, and there was no difference detected between pretreatment and posttreatment discontinuation (P = 0.100). Conclusion: A reversible decrease in renal functions was detected in patients using crizotinib. When the literature data are examined, it is thought that the reason for this decrease may be related to the increase in renal inflammation or a pseudo decrease due to the decrease in creatinine excretion. When evaluating renal functions in these patients, using noncreatine-based (iothalamate, etc.) calculations can give more accurate results.

RESUMEN

AIM: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS). PATIENTS AND METHODS: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort. RESULTS: Data of 552 adults (57.6% women, median age: 52 years) were analyzed. DCR and ORR were 43.1% and 30.8%, respectively. Median PFS was 6.7 months and OS was 13.8 months. For LMS, UPS and SS, median PFSs were 6.1, 5.9 and 7.53 months and median OSs were 15.03, 12.87 and 12.27 months, respectively. ECOG ≥ 2 was associated with poor PFS and OS. Liver metastasis was only a factor for progression. Second-line use of pazopanib (vs. front-line) was associated with better PFS, its use beyond third line predicted worse OS. Adverse events (AE) occurred in 82.7% of patients. Most common AEs were fatigue (58.3%) and anorexia (52.3%) which were graded as ≥ 3 in 8.2% and 7.4% of patients, respectively. CONCLUSION: Pazopanib is effective and well-tolerated in treatment of non-adipocytic metastatic STS. Its earlier use (at second-line), good performance status may result in better outcomes. Worldwide scientific collaborations are important to gain knowledge on rarer STS subtypes by conducting studies in larger patient populations.

RESUMEN

BACKGROUND: We investigated the clinical outcome of patients with brain metastases (BMs) from human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC) treated with lapatinib and capecitabine (LC). PATIENTS AND METHODS: A total of 203 patients with HER2+ MBC, who had progressed after trastuzumab-containing chemotherapy, were retrospectively evaluated in 11 centers between September 2009 and May 2011. 85 patients who had developed BMs before the initiation of treatment with LC were included. All patients had received prior cranial radiotherapy. All patients were treated with the combination of lapatinib (1,250 mg/day continuously) and capecitabine (2,000 mg/m(2) on days 1-14 of a 21-day cycle). RESULTS: The median follow-up was 10.5 months (range 1-38 months). An overall response rate of 27.1% was achieved, including complete response in 2 (2.4%) and partial response in 21 (24.7%) patients. Median progression-free survival was 7 months (95% confidence interval (CI) 5-9), with a median overall survival of 13 months (95% Cl 9-17). The most common side effects were hand-foot syndrome (58.8%), nausea (55.3%), fatigue (48.9%), anorexia (45.9%), rash (36.5%), and diarrhea (35.4%). Grade 3-4 toxicities were hand-foot syndrome (9.4%), diarrhea (8.3%), fatigue (5.9%), and rash (4.7%). There were no symptomatic cardiac events. CONCLUSION: LC combination therapy was effective and well-tolerated in patients with HER2+ MBC with BMs, who had progressive disease after trastuzumab-containing therapy.

RESUMEN

CONTEXT: The prognostic criteria for early-stage nonsmall cell lung cancer (NSCLC) wait to be explored. AIM: In this study, our aim was to evaluate the prognostic significance of the positron emission tomography/computed tomography (PET/CT) maximum standardized uptake value (SUVmax) value of the primary tumor in patients with a diagnosis of early-stage NSCLC who received surgical treatment. SETTINGS AND DESIGN: This was a multicenter retrospective design. MATERIALS AND METHODS: Patients who had been diagnosed with early-stage NSCLC and who underwent surgery for the condition were included in this study. The preoperative fluorodeoxyglucose (18F-FDG) PET/CT results of the patients were retrospectively accessed from their medical files. The disease-free survival (DFS) rates of patients who had SUVmax values above and below the determined cutoff value were compared. STATISTICAL ANALYSIS USED: SPSS version 22 and Kaplan-Meier method were used for statistical analysis. RESULTS: A total of 92 patients were included in the study. The median age of the patients was 60 years (range: 36-79). The determined cutoff SUVmax value of the primary tumor was 13.6. A comparison of the DFS rates of the patients with an SUVmax value above and below 13.6 revealed a significant difference in patients with Stage I (22.9 months vs. 50.3 months; P = 0.02) and Stage II (28 months vs. 40.4 months; P = 0.04), Stage I + II (43.5 months vs. 26.1 months; P = 0,02), and Stage IIIA (14.7 months vs. 13.6 months; P = 0.92) NSCLC. CONCLUSIONS: We found that in early-stage NSCLC patients, the SUVmax value of the primary mass in 18F FDG PET/CT was a prognostic indicator for the DFS rates.

RESUMEN

PURPOSE: We aimed to investigate the efficacy of 0.25 mg dose of palonosetron and granisetron in triplet antiemetic prophylaxis in breast cancer patients receiving HEC. METHODS: Patients with nonmetastatic breast cancer who received HEC [doxorubicin or epirubicin plus cyclophosphamide (AC/EC)] were enrolled in the study. The prophylactic triplet antiemetic regimens were used according to the doctor's preference during the first cycle of HEC as intravenous dexamethasone and palonosetron 0.25 mg or granisetron 3 mg on day 1 as well as oral aprepitant (125 mg on day 1 and 80 mg on days 2 and 3).The primary endpoint was complete response rate (CR) on acute and delayed chemotherapy-induced nausea and vomiting (CINV), separately. RESULTS: A total of 118 female patients were included in the study. Patients received AC (83%), EC (3%), and dose-dense AC (14%) as adjuvant (88%) or neoadjuvant (12%). The majority of patients received palonosetron (59%) containing antiemetic treatment. The CR rate on acute and delayed vomiting was very high and not statistically different in both of the arms (acute 87% vs. 96%, p = 0.089; delayed 90% vs. 92%, p = 0.489), respectively. Nevertheless, the CR rate on either acute or delayed nausea was lower than vomiting (acute 51% vs. 51%; delayed 38% vs. 29%, p = 0.203; respectively). CONCLUSIONS: This is the second study that compared a 0.25 mg dose of palonosetron with first-generation setron in triplet antiemetic prophylaxis in cancer patients receiving HEC. We could not find meaningful statistical differences between two arms, regarding CR rate on acute and delayed CINV.

RESUMEN

OBJECTIVE: Subclinical hypothyroidism is an elevation in serum thyroid-stimulating hormone (TSH) while having normal serum free thyroxine (FT4) and triiodothyronine (FT3) levels. The purpose of this prospective observational study was to evaluate the pulmonary function of patients diagnosed with subclinical hypothyroidism, both before and after treatment with thyroid hormone. METHODS: This study took place at the Medical Faculty, Celal Bayar University, Manisa, Turkey between February 2003 and June 2004. Thirty-eight patients (37 females, one male) with subclinical hypothyroidism between 20 and 65 years of age were included in the study. Most were mildly obese. Arterial blood gases and pulmonary function tests were performed before treatment with thyroid hormone, and afterwards, the TSH value reached the normal range (indicating euthyroidism). RESULTS: Oxygen saturation, but not partial oxygen pressure or partial carbon dioxide pressure, was statistically, but not clinically significantly higher after treatment with thyroid hormone (p=0.01). Pulmonary function tests were not significantly different before and after treatment with thyroid hormone. CONCLUSION: In our subclinical hypothyroidism patients, pulmonary function tests were normal and did not significantly change with thyroid hormone replacement. The advantages of thyroid hormone replacement therapy, at least regarding respiratory function, seem to be clearly present in patients with overt, clinical hypothyroidism but not in patients with subclinical hypothyroidism.

RESUMEN

Primary malignant melanomas of uterine cervix are quite rarely seen neoplasms, and long-life prognosis of patients with this disease is poor. Immunohistochemical methods and exclusion of other primary melanoma sites are used to confirm the diagnosis. As with other melanomas, cervix malignant melanomas may also cause cardiac metastases. Cardiac metastases are among rarely seen but more commonly encountered cases, compared to primary cardiac tumors. Here, we present a case of biatrial cardiac metastases in a 73-year-old patient with uterine cervix malignant melanomas. The patient underwent echocardiography, cardiac magnetic resonance imaging, and computed tomography. Our report shows the importance of advanced diagnostic techniques, such as cardiac magnetic resonance, not only for the detection of cardiac masses, but for a better anatomic definition and tissue characterization. Although the cases of malignant melanomas leading to multiple cardiac metastasis were reported in literature, the metastatic concurrence of malignant melanomas in both right and left atriums is quite rarely encountered as metastatic malignant melanomas. Also, another intriguing point in our case is that the primary lesion of our case was stemmed from uterine cervix, but not skin.

RESUMEN

BACKGROUND: The American Joint Committee on Cancer (AJCC) published a new staging system (7th edition) in 2009. In our study, we evaluated the survival results and prognostic factors among T4 local advanced non-small cell lung cancer (LA-NSCLC) patients in a large heterogeneous group, in accordance with this new system. MATERIALS AND METHODS: We retrospectively evaluated the files of 122 T4 N0-3 M0 LA-NSCLC patients, identified according to the new staging system, treated at two centers between November 2003 and June 2012. Variables correlating with univariate survival at p<0.20 were later included in multivariate Cox regression analysis. Here, selection of relevant predictors of survival was carried out in accordance with the likelihood ratio formula with p<0.05 regarded as significant. RESULTS: The median age was 60 and the median follow-up period was 17.4 months. Median overall survival (OS) was 18.3 months, the 1 year overall survival (OS) rate was 72%, and the 5 year OS rate was 28%. Statistically significant predictors of survival were (p<0.20) ECOG-PS (Eastern Cooperative Oncology Group Performance Status), age, T4 factor subgroup, stage and primary treatment in OS univariate analysis. On multivariate analysis for OS ECOG-PS (p=0.001), diagnostic stage (p=0.021), and primary treatment (p=0.004) were significant. In the group receiving non-curative treatment, the median OS was 11.0 months, while it was 19.0 months in the definitive RT group and 26.6 months in the curative treatment group. There was a significant difference between the non-curative group and the groups which had definitive RT and curative operations (respectively p<0.001 and p=0.001) in terms of OS, but not between the groups which had definitive RT and curative operations. The median event free survival (EFS) rate was 9.9 months, with rates of 46% and 19% at 3 and 5 years, respectively. On univariate analysis of EFS rate with ECOG-PS, weight loss and staging, statistical significance was found only for thorax computerized tomography (CT)+18F-fluorodeoxy-glucose positron emission tomography-CT (PET-CT) use, stage and primary treatment (p<0.20). In multivariate analysis with EFS, only the primary treatment was statistically significant (p=0.001). In the group receiving non-curative treatment, the median EFS was 10.5 months while in the curative operation group it was 14.7 months. When all the primary treatment groups were taken into consideration, grade III/IV side effect was observed in 57 patients (46.6%). Esophagitis was most prominent among those that received definitive radiotherapy. CONCLUSIONS: Independent prognostic factors among these 122 heterogeneous LA-NSCLC T4 N0-3 M0 patients were age at diagnosis, ECOG-PS, stage and primary treatment, the last also being a significant prognostic indicator of EFS. Our findings point to the importance of appropriate staging and a multidisciplinary approach with modern imaging methods in this patient group. In those with T4 lesions, treatment selection and the effective use of curative potential should be the most important goal of clinical care.

RESUMEN

BACKGROUND: Non-epithelial malignant ovarian tumors and clear cell carcinomas, Brenner tumors, transitional cell tumors, and carcinoid tumors of the ovary are rare ovarian tumors (ROTs). In this study, our aim was to determine the clinicopathological features of ROT patients and prognostic factors associated with survival. MATERIALS AND METHODS: A total of 167 patients with ROT who underwent initial surgery were retrospectively analyzed. Prognostic factors that may influence the survival of patients were evaluated by univariate and multivariate analyses. RESULTS: Of 167 patients, 75 (44.9%) were diagnosed with germ-cell tumors (GCT) and 68 (40.7%) with sex cord-stromal tumors (SCST); the remaining 24 had other rare ovarian histologies. Significant differences were found between ROT groups with respect to age at diagnosis, tumor localization, initial surgery type, tumor size, tumor grade, and FIGO stage. Three-year progression-free survival (PFS) rates and median PFS intervals for patients with other ROT were worse than those of patients with GCT and SCST (41.8% vs 79.6% vs 77.1% and 30.2 vs 72 vs 150 months, respectively; p=0.01). Moreover, the 3-year overall survival (OS) rates and median OS times for patients with both GCT and SCST were better as compared to patients with other ROT, but these differences were not statistically significant (87.7% vs 88.8% vs 73.9% and 170 vs 122 vs 91 months, respectively; p=0.20). In the univariate analysis, tumor localization (p<0.001), FIGO stage (p<0.001), and tumor grade (p=0.04) were significant prognostic factors for PFS. For OS, the univariate analysis indicated that tumor localization (p=0.01), FIGO stage (p=0.001), and recurrence (p<0.001) were important prognostic indicators. Multivariate analysis showed that FIGO stage for PFS (p=0.001, HR: 0.11) and the presence of recurrence (p=0.02, HR: 0.54) for OS were independent prognostic factors. CONCLUSIONS: ROTs should be evaluated separately from epithelial ovarian cancers because of their different biological features and natural history. Due to the rarity of these tumors, determination of relevant prognostic factors as a group may help as a guide for more appropriate adjuvant or recurrent therapies for ROTs.

RESUMEN

Lapatinib is the first dual tyrosine kinase inhibitor of human epidermal growth factor receptor type 2 (HER2/neu) and epidermal growth factor receptor (EGFR). The present study evaluated the efficacy and tolerability of the combination of lapatinib and capecitabine in patients with metastatic breast cancer (MBC) who progressed after therapy with trastuzumab, a taxane and/or anthracycline. A total of 203 patients with a median age of 48 years (range: 25-82 years) were evaluated retrospectively in 11 centres between September 2007 and May 2011. All the patients had HER2-positive MBC progressing after trastuzumab and chemotherapy including an anthracycline and/or taxane. All patients were treated with the combination of lapatinib (1250 mg/day, continuously) and capecitabine (2000 mg/m(2) on days 1 through 14 of a 21-day cycle). Data on demographics, clinical outcome, and toxicity were collected for descriptive analyses. The median follow-up was 10·7 months (range: 1-40 months). An overall response rate (ORR) of 33·4% was achieved including 7 complete responses (CR, 3·4%), 61 partial responses (PR, 30·0%), and 44 stable disease (37·9%). Clinical benefit rate of 71·3% was achieved. Median progression-free survival (PFS) was 7 months (95% CI: 6-10 months), with a median overall survival (OS) of 15 months (95% CI: 12-18 months). The most common side effects were hand-foot syndrome (46·8%), nausea (42·3%), fatigue (42·2%), anorexia (38·5%), diarrhea (31·5%), and rash (29·6%). Grade 3-4 toxicities were identified as hand foot syndrome (7·9%), diarrhea (6·9%), fatigue (5·9%), and rash (5·4%). There were no symptomatic cardiac events. Lapatinib and capecitabine combination therapy is effective and well tolerated in patients with MBC who had progressive disease after trastuzumab, taxane, and/or anthracycline therapy, as evidenced by this retrospective evaluation. Toxicity was mild to moderate with low grade 3-4 toxicity.

RESUMEN

Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm that originates from follicular dendritic cells in lymphoid follicles. FDCS has been increasingly reported in recent years. However, data on FDCS are mostly based on single case reports or case series and its natural history and standard treatment are not clear. To increase the understanding of this rare disease, we report our experience of three cases of FDCS with an analysis of the morphological and immunophenotypic characteristics, clinical course, treatment options and response to treatment. In addition, we reviewed the literature on FDCS.
