Efficacy of adjuvant capecitabine in residual triple negative breast cancer: a multicenter observational Turkish Oncology Group (TOG) study.

BACKGROUND: Triple negative breast cancer (TNBC) is characterized by high rates of recurrence, especially in patients with residual disease after neoadjuvant chemotherapy (NAC). Capecitabine is being used as standard adjuvant treatment in residual TNBC. We aimed to investigate the real-life data regarding the efficacy of capecitabine in residual TNBC. DESIGN AND METHODS: In this retrospective multicenter study, TNBC patients with residual disease were evaluated. Patients, who received standard anthracycline and taxane-based NAC and adjuvant capecitabine were eligible. Overall survival (OS), disease free survival (DFS) and toxicity were analyzed. RESULTS: 170 TNBC patients with residual disease were included. Of these, 62.9% were premenopausal. At the time of analysis, the recurrence rate was 30% and death rate was 18%. The 3-year DFS and OS were 66% and 74%, respectively. In patients treated with adjuvant capecitabine, residual node positive disease stood out as an independent predictor of DFS (p = 0.024) and OS (p = 0.032). Undergoing mastectomy and the presence of T2 residual tumor was independent predictors of DFS (p = 0.016) and OS (p = 0.006), respectively. CONCLUSION: The efficacy of capecitabine was found lower compared to previous studies. Selected patients may have further benefit from addition of capecitabine. The toxicity associated with capecitabine was found lower than anticipated.

Early and Long-Term Morbidity and Mortality Following Pancreaticoduodenectomy for Periampullary Tumors in Elderly Patients.

AIM: The growing elderly population is facing an increasing risk of cancers, consequently raising the pancreatic cancer surgery rate. This study aimed to determine whether advanced age is a risk factor for morbidity and mortality following pancreaticoduodenectomy (PD) for periampullary tumors. MATERIALS AND METHODS: The present study included 90 patients who underwent PD for periampullary tumors. Patients were divided into two age-related groups, including those aged 60-74 years (n = 60) (Group 1) and those aged ≥75 years (n = 30) (Group 2). Each patient's characteristics, perioperative features, morbidity, and long-term results were evaluated retrospectively. RESULTS: In both univariate and multivariate logistic regression analyses, old age (≥75 years) was not a risk factor for morbidity and hospital mortality. The multivariate analysis demonstrated that male gender (p = 0.008), pancreatic duct diameter (<3 mm) (p < 0.001), and length of hospital stay (p = 0.005) were independent risk factors for pancreatic fistula post-operation and reoperation. Additionally, hospital mortality was significantly associated with reoperation (p = 0.011). The overall median survival was 27 ± 4.1 (18.8-35.1) months. Lymph node positivity (p < 0.001), neural tumor invasion (p = 0.026), and age ≥75 years (p = 0.045) were risk factors affecting the overall survival rate. Moreover, there was no statistically significant difference in terms of PD rates during the Coronavirus disease-19 (COVID-19) period among groups, and PD during this period was not related to the occurrence of pancreatic fistula. CONCLUSION: PD can be performed effectively in selected elderly patients with tolerable morbidity and mortality rates.

A grounded theory of resilience experiences of women with gynecological cancer.

PURPOSE: The present study aims to develop an explanatory framework to gain a deeper understanding of the resilience process in women diagnosed with gynecological cancers. METHOD: Informed by Salutogenesis Model, a Straussian-grounded theory study was conducted. In-depth interviews were conducted with 20 women with gynecological cancer between January and August 2022. Data were analyzed using open, axial, selective coding, and constant comparative methods. RESULTS: The core category encapsulated that most women defined resilience as having a dynamic process that could be promoted throughout the process. However, they expressed that they needed "individual resources for resilience" and "generated resources by the supportive interventions" to be resilient. They emphasized that these resources should make the process manageable, meaningful, and comprehensible to promote resilience. Furthermore, they defined in detail which components should be included in supportive interventions. They stated "some reflections of resilience on their cancer process" and "life gains from the process." CONCLUSION: This study developed a grounded theory that provides a guideline for healthcare professionals on how women could be encouraged to have resilience and what is the importance of resilience on women's cancer process and their lives. Salutogenesis may help to understand the resilience process in women with gynecological cancer and provides direction for how healthcare professionals should shape their clinical interventions to promote the resilience process.

Efficacy of subsequent treatments in patients with hormone-positive advanced breast cancer who had disease progression under CDK 4/6 inhibitor therapy.

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.

A New Prognostic Index in Young Breast Cancer Patients.

OBJECTIVE: To evaluate the prognostic role of pan immune-inflammation value (PIV) in young breast cancer patients. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Medical Oncology, Afyon University of Health Sciences, School of Medicine Hospital, Turkey, between January 2010 and December 2020. METHODOLOGY: Patients who were under the age of 40 years at the time of diagnosis were included. Patients' characteristics and disease parameters were recorded. PIV was calculated according to (neutrophil x platelet x monocyte/lymphocyte, i.e. NxPxM/L) formula. Since a cut-off value with max sensitivity and specificity could not be obtained with ROC analysis, the median value of PIV was used as cut-off value. The relationship between PIV and pathological parameters was evaluated by ROC curves. The Kaplan-Meier method was used for OS and the log-rank test was used to evaluate the survival differences between the two groups, according to the optimal cut-off point. RESULTS: Based on the PIV cut-off value of 121 (49.8%) patients were in the low PIV and 122 (50.2%) patients were in the high PIV group. The patients in the high PIV group had a statistically significantly more advanced AJCC stage, and were younger patients. In the survival analysis, it was observed that the survival was worse in the high PIV group but this difference did not reach statistical significance (p=0.112). CONCLUSION: Higher PIV levels at the time of diagnosis can be another prognostic marker. However, to clarify the PIV prognostic value, it needs to be validated in larger, multi-centre prospective clinical studies. Key Words: Breast cancer, Pan immune-inflammation value (PIV), Prognosis, Young women.

The Efficacy and Safety of Treatment Regimens Used in the First-Line Setting in Metastatic Pancreatic Cancer Patients: A Multicenter Real-Life Study.

OBJECTIVE: The aim of the study is to compare the efficacy and safety of 3 chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer. METHODS: A total of 218 patients were included in this multicenter study. Gemcitabine (Gem, n = 71), gemcitabine-cisplatin (Gem-Cis, n = 91), and FOLFIRINOX (a combination of leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin [FFX], n = 56) treatments were compared. RESULTS: Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (P = 0.010). Median progression-free survival (8.4 vs 4.6 and 5.5 months, respectively, P < 0.001) and overall survival (16.4 vs 8.1 and 8.7 months, respectively, P = 0.002) were significantly longer in the FFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46 (64.8%), 56 (61.5%), and 49 (87.5%) patients in the Gem, Gem-Cis, and FFX groups, respectively (P = 0.003). CONCLUSIONS: In our study, FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.

Has the COVID-19 Pandemic Increased Mortality Among Patients with Cancer Receiving Systemic Anticancer Treatments?

OBJECTIVE: To evaluate the mortality rates in patients receiving anticancer therapy in the coronavirus disease-19 (COVID-19) pandemic period. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Medical Oncology, Sakarya University Training and Research Hospital, Sakarya, Turkey, from December 2017 to May 2020. METHODOLOGY: Only patients who received chemotherapy and immunotherapy were selected and enrolled in the study. All patients (n=3,204) were divided into three groups, namely the first group (1st December 2017-31st May 2018, n=918), second group (1st December 2018-31st May 2019, n=1,147), and the pandemic period group (PPG) (1st December 2019-31st May 2020, n=1,139), according to the period during which they received anticancer treatment. The clinical and demographic characteristics and mortality rates of these three groups of patients were compared. RESULTS: The median age of the total of 3,204 patients was 61 (53-69). In this study, 51.1% (n=1,636) were females and 48.9% were males. The mortality rates were 13.5% (n=124) in the first group, 13.4% (n=154) in the second group, and 13.0% (n=148) in the PPG, respectively. Overall mortality rates did not differ among patients with cancer in the three different six-month periods analysed (p = 0.931). CONCLUSION: There was no unexpected increased in mortality rate among patients undergoing cancer therapy during the COVID-19 pandemic as compared to the previous years of the same timeline. No increase in monthly mortality rates among patients receiving anti-cancer treatment were demonstrated during the pandemic period.

Comparison of real-life data of abiraterone acetate and enzalutamide in metastatic castration-resistant prostate cancer.

To compare enzalutamide (E) and abiraterone acetate (AA) in terms of efficacy, survival and to characterize prognostic factors affecting survival in metastatic castration-resistant prostate cancer (mCRPC) patients. A total of 250 patients treated with E or AA in 5 centers were included. The number of patients with no prostate specific antigen (PSA) decline was higher in the AA group than that in the E group, and the proportion of patients with a PSA decline of ≥ 50% was higher in the E group (p = 0.020). Radiological progression free survival (rPFS) and overall survival (OS) were significantly longer in the E group when compared to that in the AA group (p < 0.001 and p = 0.027, respectively). In the E group, rPFS was significantly longer than that in the AA group in both pre- and post-docetaxel settings (p = 0.010 and p = 0.003, respectively). OS was similar in the pre-docetaxel setting; but in the post-docetaxel setting, E group had a significantly longer OS than the AA group (p = 0.021). In the multivariate analysis performed in the whole patient group, we found that good prognostic factors for rPFS were E treatment, being ≥ 75 years and a PSA decline of ≥ 50% while there was no factor affecting OS. With longer OS and PFS, E seems to be more suitable for mCRPC patients in the post-docetaxel setting than AA.

Comparative assessment of three different second-line regimens in chemotherapy resistant / refractory small-cell lung cancer.

PURPOSE: Small cell lung cancer (SCLC) patients unresponsive or relapsing within 90 days following frontline chemotherapy have poor prognosis and they should be treated with different chemotherapy regimens other than those used in the first-line regimen. Currently there is no globally accepted standard chemotherapeutic regimen for the treatment of these patients. This retrospective study was designed to compare CAV (Cyclophosphamide, Doxorubicin, Vincristine), weekly topotecan and weekly irinotecan regimens and to evaluate the efficacy of the three regimens in patients with chemotherapy resistant/refractory (CRR) SCLC. METHODS: A total of 67 CRR-SCLC patients, who were treated with CAV, weekly topotecan and weekly irinotecan were reviewed for weekly irinotecan (27 for 60 mg/m2 intravenously on days 1, 8 and 15 of a 28-day cycle,24 for CAV (Cyclophosphamide 750 mg/m² on day 1, Doxorubicin 50 mg/m² on day 1 and Vincristine 1.4mg/m2 on day 1 every 3 weeks), 16 for weekly topotecan (4 mg/m2 intravenously on days 1, 8 and 15 of a 28-day cycle). RESULTS: The median follow-up time was 12.45 months, there was no difference about disease control rates (DCR) between three chemotherapy regimens (DCR; 25.9% with irinotecan, 29.2% with CAV and 31.3% with topotecan, p=0.92). Objective response rates (ORR) for irinotecan, CAV and topotecan groups were 3,7%, 8,8%, and 0%, respectively (p=0.63). Median progression free survival (PFS) and overall survival (OS) were similar according to irinotecan, CAV, and topotecan (PFS: 1.93 months, 2.30 months and 3.45 months; OS: 2.89 months, 4.79 months and 5.81 months, respectively). The adverse events were generally mild and manageable for both hematological and nonhematological toxicities in all three arms. CONCLUSIONS: Weekly irinotecan, CAV and weekly topotecan are similarly effective and safe chemotherapy protocols for the treatment of CRR-SCLC patients.

No increase in monthly mortality rates among patients receiving anti-cancer treatment were demonstrated during the pandemic period.

The comparison of FOLFOX regimens with different doses of 5-FU for the adjuvant treatment of colorectal cancer: a multicenter study.

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.

Effect of Radioactive Iodine Treatment on Saliva Rate in the Early Post-treatment Period.

OBJECTIVE: To investigate the effects of radioactive iodine therapy (131I) on saliva production rate in the early post-treatment period. STUDY DESIGN: Descriptive, analytical study. Place and Duration of Study: Department of Endocrinology, Ankara Diskapi Yildirim Beyazit Research and Education Hospital, Ankara, Turkey from January to December 2017. METHODOLOGY: A total of 40 patients, who received radioactive iodine therapy after total thyroidectomy, were included in the study. Stimulated and unstimulated saliva levels were measured before and after treatment, using a scaled and sterile plastic tube. RESULTS: The study group was comprised of three males (7.5%) and 37 females (92.5%) with a mean age of 44.15 ±10.2 years (range 26-66 years). The median values of all non-stimulated saliva before and after RAI treatment were 2.0 ml / minute (1.13-2.88) and 2.0 ml / minute (1.63-4.00), respectively; and the difference was not statistically significant (p=0.11). Similarly, there were no statistically significant differences in the median values of stimulated saliva before and after RAI treatment (median=7.0 ml/min and 7.5 ml/dk, respectively; p=0.88). CONCLUSION: Radioactive iodine treatment did not cause sialadenitis and did not affect the saliva production rates in the early post-treatment period. Key Words: Radioactive iodine, Stimulated saliva, Unstimulated saliva.

Long-term outcomes of prolonged bisphosphonates more than 2 years in bone metastatic breast cancer: risk vs benefit.

BACKGROUND: Bisphosphonates are the mainstay therapeutic options for prevention of skeletal-related events and generally used for up to 2 years in bone metastatic cancer patients. AIM: We aimed to evaluate the long-term outcomes of prolonged (> 2 years) bisphosphonate usage in bone metastatic breast cancer (BMBC) patients. METHODS: Ninety-nine BMBC patients who had prolonged bisphosphonates were evaluated retrospectively for long-term outcomes and survival rates. RESULTS: Median duration of bisphosphonate therapy was 46.8 (24-198) months. Seven patients had bisphosphonate-related adverse events (osteonecrosis of the jaw (ONJ) (n = 6), ONJ and renal failure (n = 1)). Bisphosphonate was switched to another one because of bone metastasis progression in more than one-third of the patients (n = 36, 36.3%). The patients who had bisphosphonate switch therapy had statistically significant longer overall survival (p < 0.01). Neither duration nor type of bisphosphonates had effect on frequency of bisphosphonate-related adverse events. CONCLUSION: Bisphosphonates might be prolonged for more than 2 years in BMBC patients with an acceptable toxicity profile. In addition, bisphosphonates switch therapy should be preferred in those with progressive bone metastasis since it might contribute to better survival despite bisphosphonates could not have been shown to have survival benefit in previous studies.

The prognostic and predictive significance of plasma type 1 plasminogen activator inhibitor and endoglin in metastatic colorectal cancer patients treated with bevacizumab-containing chemotherapy.

AIM: This study aims to evaluate the prognostic and predictive value of plasma plasminogen activator inhibitor-1 (PAI-1) and endoglin in metastatic colorectal cancer (mCRC) patients receiving chemotherapy with bevacizumab. MATERIALS AND METHODS: Between April 2012 and September 2013, 47 mCRC patients with a mean age of 58.5 ± 9.6 years were included in the study. Male-to-female ratio was 29/18. The baseline and posttreatment plasma PAI-1 and serum endoglin levels after 3 cycles of bevacizumab-containing chemotherapy were evaluated. The percent change between baseline and posttreatment levels after treatment was also recorded. RESULTS: The median follow-up duration was 26.6 months (range 1.8-70.2 months). The clinical benefit rate was 70% (partial response [32%], stable disease [38%]). Overall survival was 20.8 ± 1.5 months. The patients with progressive disease had statistically significantly higher baseline PAI-1 level (57.9 pg/mL vs. 29.9 pg/mL, P = 0.036). The percent change of the plasma PAI-1 level after the third cycle of treatment was also statistically significantly lower in those with clinical benefit (P = 0.035). However, there was no statistically significant difference in endoglin level and its change after therapy with respect to the response to treatment (P = 0.771 and P = 0.776, respectively). Plasma PAI-1 level had no statistically significant effect on survival (P = 0.709). CONCLUSION: Baseline plasma PAI-1 level and its percent change with bevacizumab were shown to have statistically significant predictive value for the response to therapy whereas serum endoglin had no statistically significant predictive value for the response to therapy. However, neither PAI-1 nor endoglin had prognostic significance in mCRC.

Retrospective evaluation of premenopausal hormone-sensitive breast cancer patients treated with adjuvant gonadotropin-releasing hormone analogue: Anatolian Society of Medical Oncology (ASMO) study.

AIM: The goal of this study is to evaluate possible factors affecting the survival of patients treated with gonadotropin-releasing hormone (GnRH) analogues. METHODS: Demographic characteristics, treatment modalities, overall survival (OS) and the possible factors affecting the survival a total of 554 premenopausal breast cancer patients in Turkey evaluated retrospectively. RESULTS: The median duration of GnRH analogues use was 22 ± 13.6 (range, 1-87) months. Patients were divided into three groups according to the duration of GNRH analogues use; 4-12 months (Group A), 13-24 months (Group B) and ≥25 months (Group C). Overall, 530 patients were analyzed; 23.2%, 45.8%, 30.9% of the patients were in Group A, B and C, respectively. The median follow-up duration was 34 ± 30.3 (range, 4-188) months. The OS in patients ≤35 years of age was found to be significantly longer than that of patients >35 years of age in Group B (log rank, P = 0.023). The disease-free survival of the patients in Group A was significantly shorter than that of patients in Group C (log rank, P = 0.003). The OS of Group A patients was significantly shorter in comparison to that of Group B and Group C patients (log rank, P = 0.000) and the OS of Group B patients was significantly shorter than Group C (log rank, P = 0,000). CONCLUSION: There is currently no definite data on the optimal duration of GnRH analogues use. One of the important results of this study that will provide an insight to the future studies is the improvement gained in OS by the increase in the duration of GnRH analogues use.

Clinical outcomes and prognostic factors of adult's Ewing sarcoma family of tumors: single center experience.

AIM OF THE STUDY: Aim of the study was to investigate the demographics of Ewing sarcoma family of tumours (ESTF) patients, treatment alternatives, clinical outcomes, and prognostic factors for survival. MATERIAL AND METHODS: We retrospectively reviewed 39 patients with ESFT who were admitted to our institute between September 2008 and September 2012. RESULTS: The patients included 32 (82.1%) males and seven (17.9%) females of median age 24 (range, 18-66) years. Among the 27 patients with a primary osseous localization, 17 (43.5%) had a central axis localization. Fifteen patients (38.5%) had metastases at the time of diagnosis. Patients were followed up for a median period of 18 (range, 2-134) months. The median event-free survival (EFS) was 23 (range, 1-64) months, and the 1- and 4-year EFS were 60% and 48%, respectively. The median overall survival (OS) was 91 (range, 1-188) months, and the 1- and 4-year OS were 78% and 54%, respectively. Gender, age, primary tumor site, and local treatment modalities, either alone or in combination, did not have a significant effect on OS (p = 0.210, p = 0.617, p = 0.644, and p = 0.417, respectively). In contrast, osseous site of peripheral localization, limited stage, and metastasis to the bone significantly affected OS (p = 0.015, p < 0.001, and p = 0.042, respectively). CONCLUSIONS: ESFTs are aggressive tumors with a high rate of relapse and metastatic potential. Patients with peripheral bone involvement and limited stage had a good prognosis. Appropriate surgical resection, radiotherapy, and aggressive chemotherapy regimens are recommended.

Outcomes of Adolescent and Adult Patients with Lung Metastatic Osteosarcoma and Comparison of Synchronous and Metachronous Lung Metastatic Groups.

Osteosarcomas with lung metastases are rather heterogenous group. We aimed to evaluate the clinicopathological characteristics and outcomes of osteosarcoma patients with lung metastases and to compare the synchronous and metachronous lung metastatic groups. A total of 93 adolescent and adult patients with lung metastatic osteosarcoma, from March 1995 to July 2011, in a single center, were included. Sixty-five patients (69.9%) were male. The median age was 19 years (range, 14-74). Thirty-nine patients (41.9%) had synchronous lung metastases (Group A) and 54 patients (58.1%) had metachronous lung metastases (Group B). The 5-year and 10-year post-lung metastases overall survival (PLM-OS) was 17% and 15%, respectively. In multivariate analysis for PLM-OS, time to lung metastases (p = 0.010), number of metastatic pulmonary nodules (p = 0.020), presence of pulmonary metastasectomy (p = 0.007) and presence of chemotherapy for lung metastases (p< 0.001) were found to be independent prognostic factors. The median PLM-OS of Group A and Group B was 16 months and 9 months, respectively. In Group B, the median PLM-OS of the patients who developed lung metastases within 12 months was 6 months, whereas that of the patients who developed lung metastases later was 16 months. Time to lung metastases, number and laterality of metastatic pulmonary nodules, chemotherapy for lung metastatic disease and pulmonary metastasectomy were independent prognostic factors for patients with lung metastatic osteosarcoma. The best PLM-OS was in the subgroup of patients treated both surgery and chemotherapy. The prognosis of the patients who developed lung metastases within 12 months after diagnosis was worst.

Progesterone receptor status in determining the prognosis of estrogen receptor positive/ HER2 negative breast carcinoma patients.

PURPOSE: To evaluate the impact of progesterone receptor (PR) status on estrogen receptor (ER)-positive and HER2-negative breast cancer. METHODS: A total of 1673 operable breast cancer patients, diagnosed from June 1984 to June 2011 were retrospectively reviewed and 400 patients with ER-positive and HER2-negative tumors were identified and evaluated. ER-positive and HER2-negative patients were classified into two groups: group A: ER+/PR-/HER2- and group B : ER+/PR+/HER2- according to PR status. RESULTS: Median follow-up was 14.2 years (range 10.1-18.2). The ratio of postmenopausal patients was significantly higher in group A (68.2%, p=0.015). Grade 1 tumor and stage I disease were significantly higher in group B (15%, p=0.007 and 15%, p=0.005, respectively). Mean overall survival (OS) and disease free survival (DFS) were significantly better in group B (15.3±1.5 years vs 8.7±0.8 years, p=0.032; 10.5±1.6 years vs 5.7±0.5 years, p=0.022) as compared with group A. Relative risk for recurrence and death were two-fold higher in group A (p=0.05 and p=0.01, respectively). CONCLUSION: PR status exerts a significant impact on prognosis of ER+/HER2- breast cancer.

Treatment decision plans matter in elderly patients with gastrointestinal cancer: suboptimal or optimal?

PURPOSE: Aging is an important risk factor for cancer. Molecular changes and defective immunity associated with aging result in increased susceptibility to many carcinogens of the gastrointestinal system (GIS). Comorbidities and changes in drug metabolism in elderly patients make the treatment of GIS cancers difficult. METHODS: Between January 2009 and December 2012, a total of 790 patients diagnosed with GIS cancers were retrospectively evaluated. Among them, 357 patients aged ≥ 65 years constituted the study population in which the patient characteristics, disease location, TNM stage, ECOG PS, co-morbidities, chemotherapy regimens and overall survival (OS) were assessed. RESULTS: The patient median age was 71 years (range 65-94). Cancer localizations were colorectal cancer (CRC), gastric cancer, and the pancreaticobiliary system (PBS) cancer in 178 (49.9%), 124 (34.7%), and 55 (15.4%) patients, respectively. A total of 260 (69%) patients underwent chemotherapy: 167 (64.3%) patients received optimal chemotherapy, and 93 (35.7%) suboptimal chemotherapy. The median OS was 47, 14, and 11 months in CRC, gastric, and PBS cancers, respectively. OS was better in the optimally-treated group than in the suboptimally-treated group among patients with all types of cancer. OS was 67 vs 19 months (p<0.001), 17 vs 8 months (p=0.004), and 12 vs 10 months (p=0.46) in CRC, gastric, and PBS cancers in the optimal and suboptimal chemotherapy groups, respectively. Multivariate analysis showed that the disease stage in all cancer types and optimal chemotherapy in the CRC group were important predictors of survival (p<0.001 and p=0.021, respectively). CONCLUSION: Cancer is usually in advanced stage at the time of diagnosis in these elderly patients and screening programs might improve outcomes in this age group. Patients with GIS cancers (especially CRC and gastric cancer) should be encouraged to receive optimal chemotherapy regimens.
