Randomized, Double-Blind, Placebo-Controlled Clinical Trial of Concurrent Use of Crocin During Chemoradiation for Esophageal Squamous Cell Carcinoma.

Crocin is the major active carotenoid of saffron (Crocus sativus L.). Its pluripotent effects have led to a growing body of literature investigating its antitumor properties as well as its diverse potentials for mood stabilization, normal tissue protection, and inflammation reduction; However, there is a gap in clinical trials testing this substance in cancer patients. In this randomized, double-blind, placebo-controlled clinical trial, patients with newly diagnosed esophageal squamous cell carcinoma were randomly assigned to either 30 mg/day of crocin or placebo, prescribed during the neoadjuvant chemo-radiotherapy. The primary endpoints were pathological response and toxicity, and secondary endpoints were depression and anxiety levels and survival analysis.

The influence of patient positioning and immobilization equipment on MR image quality and image registration in radiation therapy.

INTRODUCTION: MRI is preferred for brain tumor assessment, while CT is used for radiotherapy simulation. This study evaluated immobilization equipment's impact on CT-MRI registration accuracy and MR image quality in RT setup. METHODS: We included CT and MR images from 11 patients with high-grade glioma, all of whom were immobilized with a thermoplastic mask and headrest. T1- and T2-weighted MR images were acquired using an MR head coil in a diagnostic setup (DS) and a body matrix coil in RT setup. To assess MR image quality, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were considered in some dedicated regions of interest. We also evaluated the impact of immobilization equipment on CT-MRI rigid registration using line profile and external contour methods. RESULTS: The CNR and SNR reduction was in the RT setup of imaging. This was more evident in T1-weighted images than in T2-weighted ones. The SNR decreased by 14.91% and 12.09%, while CNR decreased by 25.12% and 20.15% in T1- and T2-weighted images, respectively. The immobilization equipment in the RT setup decreased the mean error in rigid registration by 1.02 mm. The external contour method yielded Dice similarity coefficients (DSC) of 0.84 and 0.92 for CT-DS MRI and CT-RT MRI registration, respectively. CONCLUSION: The image quality reduction in the RT setup was due to the imaged region's anatomy and its position relative to the applied coil. Furthermore, optimizing the pulse sequence is crucial for MR imaging in RT applications. Although the use of immobilization equipment may decrease the image quality in the RT setup, it does not affect organ delineation, and the image quality is still satisfactory for this purpose. Also, the use of immobilization equipment in the RT setup has increased registration accuracy.

Significance of the Pretreatment Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in Predicting the Response to Neoadjuvant Chemotherapy and Survival Rates in Extremity Osteosarcoma: A Multicentre Prospective Study.

OBJECTIVES: We aimed to assess the effects of pretreatment neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios on the response to neoadjuvant chemotherapy and survival rates in patients with extremity osteosarcoma. PATIENTS AND METHODS: Patients with high-grade osteosarcoma admitted to oncologic centers affiliated with Iran University of Medical Sciences, Tehran, Iran from 2015 to 2021 were evaluated retrospectively to assess the impact of complete blood count-related parameters on the pathologic response after neoadjuvant chemotherapy. Then, patients were followed up prospectively to evaluate the survival rates. All patients received at least three cycles of cisplatin/doxorubicin regimen, preoperatively. In this study, the cut-off values for high neutrophil-to-lymphocyte and high platelet-to-lymphocyte ratio were considered 3.28 and 128, respectively. RESULTS: One hundred eighty-six patients were enrolled. Patients with high neutrophil-to-lymphocyte ratio and high platelet-to-lymphocyte ratio had a significantly lower overall survival rates (20.7 [95% CI 18-23.5] month vs. 34.6 [95% CI 33.2-36], p = 0.003 and 21.9 [95% CI 20.2-23.6] month versus 35.3 [95% CI 33.9-36.7], p = 0.002; respectively). Moreover, disease-free survival of patients with high platelet-to-lymphocyte ratio was worse than patients with low platelet-to-lymphocyte ratio (20.4 [95% CI 18.4-22.4] month vs. 32.7 [95% CI 30.8-34.7], p = 0.02). CONCLUSION: Our study showed that neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios at the baseline can predict the survival of patients with high-grade osteosarcoma.

Immunogenicity and Safety of the Inactivated SARS-CoV-2 Vaccine (BBIBP-CorV) in Patients with Malignancy.

OBJECTIVE: To evaluate the safety and immunogenicity of the inactivated SARS-CoV-2 vaccine in cancer patients. MATERIAL AND METHOD: 364 cancer patients who received two doses of vaccine were enrolled. The presence of SARS-CoV-2 anti-Spike protein IgG and neutralizing antibody 2 months following vaccination were measured by ELIZA. RESULTS: Injection site pain and fever were the most common local and systemic side effects. The overall seroconversion rate was 86.9% that was lower in older age, those with hematological malignancies and chemotherapy receivers. CONCLUSION: The result of study confirmed the safety and short-term efficacy of inactivated vaccine in patients with malignancies.

Clinical Characteristics and Outcomes of COVID-19 in 1294 New Cancer Patients: Single-Center, Prospective Cohort Study from Iran.

OBJECTIVE: To determine the clinical characteristics and outcomes of COVID-19 in a large cohort of new cancer patients referred to an oncology clinic in the north of Iran. METHODS: During the 20-month COVID-19 pandemic, new cancer patients were followed-up. Demographic, pathologic, and clinical variables were collected for each patient. COVID-19 was confirmed based on a positive polymerase chain reaction test. Analyses were performed using the STATA version 14.0 at a significance level of 0.05. RESULTS: In this study, 1294 new cancer patients were followed for 24 months (mean age: 58.7 years [range 10-95]). During the study period, COVID-19 was diagnosed in 9.4% of the patients with hospitalization rate of 3.4%, an ICU admission rate of 0.7%, and COVID-19 mortality rate of 4.9%. Hematological malignancies (ORU= 2.6, CI95% 1.28-5.34), receiving palliative treatments (ORA=3.03, CI95% 1.6-5.45) and receiving radiotherapy (ORA=2.07, 1.17-3.65) were the most common predictive factors of COVID infection in cancer patients. Also, the COVID mortality was higher in brain cancer patients (p = 0.07), metastatic disease (p = 0.01) and patients receiving palliative treatments (p = 0.02). CONCLUSION: In patients suffering from cancer, COVID-19 infection can be predicted by cancer type, palliative care, and radiotherapy in cancer patients. Furthermore, brain cancers, metastasis, and palliative care were all associated with COVID-19-related mortality.

Multicenter Study of Antibody Seroprevalence against COVID-19 in Patients Presenting to Iranian Cancer Centers after One Year of the COVID-19 Pandemic.

Patients with cancer are at significantly greater risk of COVID-19 and its complications than the general population. Since IgG antibodies remain detectable well after infection with the SARS-CoV-2 virus, seroprevalence can be used to estimate the proportion of the cancer population previously infected and potentially immune to SARS-CoV-2. The current study is a multi-center, prospective observational study to assess the seroprevalence of SARS-CoV-2 IgG antibody in a cancer population referred for vaccination between April and June 2021. Of a total of 270 adult patients with cancer accrued, 16% reported a history of COVID-19 more than four weeks previously confirmed by PCR. At the same time, serologic positivity for SARSCoV2 IgG was found in 29% of patients prior to vaccination including nearly 20% of patients without a history of confirmed COVID-19. Seropositivity was significantly greater in females consistent with higher rates in patients with breast cancer and gynecologic cancers. A seroconversion rate of 79.5% was observed in cancer patients with a history of PCR confirmed COVID-19, less than observed in the general population. In multivariable analysis, gender and prior history of COVID-19 were both independently associated with seropositivity prior to vaccination. Follow-up is continuing of this cohort of patients with cancer following vaccination to assess antibody and clinical outcomes.

Oral silymarin formulation efficacy in management of AC-T protocol induced hepatotoxicity in breast cancer patients: A randomized, triple blind, placebo-controlled clinical trial.

BACKGROUND: Chemotherapeutic agents, with or without other drugs and radiation, may cause indirect or direct hepatotoxicity. Doxorubicin-induced hepatotoxicity (DIH) is a major health concern in cancer patients receiving this cytotoxic drug that is mostly resulted from the production of reactive oxygen species leading to transient or permanent liver damages. Silymarin, a flavonoid extracted from the Silybum marianum, exhibits antioxidant and anti-inflammatory activities. PURPOSE: This study aimed to investigate the clinical efficacy of systemic administration of silymarin in management of chemotherapy induced hepatotoxicity in patients with non-metastatic breast cancer who received doxorubicin/cyclophosphamide-paclitaxel (AC-T) regimen.Material: In this randomized, triple blind, placebo-controlled clinical trial, 30 patients who received AC-T who fulfilled the inclusion criteria were randomly allocated to silymarin (n = 15) or placebo (n = 15) groups to receive oral silymarin 140 mg three times a day or placebo tablets, respectively. Fatty liver severity was assessed by liver ultrasound imaging and FibroScan® and also measurement of liver function tests before and after the intervention. RESULTS: There was a non-significant trend toward more severe liver involvement in placebo group comparing to the silymarin group after intervention based on ultrasonography (p = 0.083). Besides, in silymarin group, hepatic involvement grade based on ultrasonography considerably reduced after intervention (p = 0.012). However, no difference was found between two groups based on FibroScan and liver function tests. CONCLUSION: Oral administration of silymarin could significantly reduce hepatotoxicity severity after 1 month of treatment in non-metastatic breast cancer patients treated with AC-T regimen.

The Relationship between Lung and Heart Two-Dimensional Parameters and Three-Dimensional Dose-Volume Data in Adjuvant Radiotherapy for Breast Cancer.

Background: Two-dimensional (2D) radiographic parameters have been used to estimate the amount of heart and lung irradiated for minimizing heart and lung complications in breast cancer patients. The aim of this study was to investigate the correlation between traditionally used 2D radiographic and dose-volume parameters during adjuvant radiotherapy of breast cancer. Methods: In this cross-sectional study, we analyzed 121 female patients treated with breast-conserving surgery (BCS) or modified radical mastectomy (MRM) and 3D conformal radiotherapy (3DCRT) using two-field radiotherapy (2FRT) or three-field radiotherapy (3FRT) technique. All patients underwent computed tomography (CT)-planning. Two-D parameters, including central lung distance (CLD), maximum lung depth (MLD), maximum heart length (MHL), maximum heart distance (MHD), and chest wall separation (CWS), were measured using digitally reconstructed radiographs (DRR) and CT images. DVHs for lung, heart, and target were created. The Pearson correlation test was used to evaluate the correlation between 2D radiographic and dose-volume parameters. Results: There was a correlation between CLD and ipsilateral lung V5-20Gy and Dmean and between MLD and ipsilateral lung V5-20Gy. In 2FRT, only moderate correlation between CLD and ipsilateral lung V20Gy (r = 0.453, P = 0.003) and between MLD and ipsilateral lung V20Gy (r = 0.593, P <0.001) were observed. Poor correlation of MHL and heart V25Gy (r = 0.409, P = 0.007) was seen only in 3FRT. There was a correlation between MHD and heart dose-volume data, with a strong correlation between MHD and heart V5-25Gy and Dmean (r = 0.875-0.934, P<0.001) in the 2FRT group. No correlation between CWS and breast Dmax was found. Conclusion: There was a correlation between 2D parameters (i.e., CLD, MLD, and MHD) and the heart and lung dose-volume parameters during adjuvant breast radiotherapy. Although CLD was correlated to ipsilateral lung V5-20Gy and Dmean, the correlation between CLD and ipsilateral lung V20Gy was greater than other dose-volume parameters. MHD provided a close estimation of heart dose-volume parameters.

Low-dose radiation therapy (LDRT) for COVID-19 and its deadlier variants.

Coronavirus variants are gaining strongholds throughout the globe. Despite early signals that SARS-CoV-2 coronavirus case numbers are easing up in the United States and during the middle of a (not so easy) vaccination roll out, the country has passed a grim landmark of 600,000 deaths. We contend that these numbers would have been much lower if the medical community undertook serious investigations into the potential of low doses of radiation (LDRT) as a mainstream treatment modality for COVID-19 pneumonia. LDRT has been posited to manifest anti-infectious and anti-inflammatory properties at doses of 0.3-1.0 Gy via the activation of the Nrf-2 pathway. Although some researchers are conducting well-designed clinical trials on the potential of LDRT, the deep-rooted, blind, and flawed acceptance of the Linear No-Threshold (LNT) model for ionizing radiation has led to sidelining of this promising therapy and thus unimaginable numbers of deaths in the United States.

Amelioration of anxiety, depression, and chemotherapy related toxicity after crocin administration during chemotherapy of breast cancer: A double blind, randomized clinical trial.

The effects of saffron (Crocus sativus L.) on mood disorders have already been established. More recently, its anti-neoplastic effects have provoked a great attention. This study aims to assess the effects of crocin administration during doxorubicin-based chemotherapy of breast cancer on anxiety, depression, and chemotherapy toxicity profile. Seventy-two patients with non-metastatic Her2/neu positive or triple negative breast cancer were enrolled and randomly assigned to receive either 30 mg/day of crocin or placebo during chemotherapy [2:2]. Beck's Depression and Anxiety Inventories were used at baseline and end of the trial. In addition, the ECOG Common Toxicity Criteria were applied to assess chemotherapy side-effects. After the intervention, the degree of anxiety and depression decreased significantly in the crocin group (p = .001 for both) and increased significantly in the placebo-group (p = .006 and p = .036, respectively). There were significantly higher grade II-IV leukopenia (47.2% vs. 19.4%, p = .012) in the crocin group, and grade II-IV hypersensitivity-reaction (30.6% vs. 5.6%, p = .006) in addition to neurological disorders (66.7% vs. 41.7%, p = .03) in the placebo-group. The results indicate that using crocin during chemotherapy in patients with breast cancer has ameliorated anxiety and depression. Moreover, leucopenia increased whereas hypersensitivity reaction and neurological disorders decreased in the crocin group. In addition, a trend toward survival improvement was observed, which is going to be investigated on longer follow up.

Overexpression of cancer-testis antigen melanoma-associated antigen A1 in lung cancer: A novel biomarker for prognosis, and a possible target for immunotherapy.

AIM: We investigated melanoma-associated antigen A1 (MAGE-A1) expression in lung cancer tissues and its correlation with prognostic factors. MATERIALS AND METHODS: In this cross-sectional study, samples from 101 patients with lung cancer were obtained between 2007 and 2014 and stained for MAGE-A1 by immunohistochemistry. Correlation with prognostic factors was assessed by t test, and χ 2 , and Pearson's tests. RESULTS: Eighty non-small-cell lung cancer (NSCLC) and 21 small-cell lung cancer specimens were stained for MAGE-A1. MAGE-A1 was detected more commonly in adenocarcinomas and was expressed more frequently in male and patients >60 years. CONCLUSIONS: MAGE-A1 was found in several lung cancer patients. MAGE-A1 was expressed more commonly in NSCLC, elderly, and men. Further investigations are needed to assess MAGE-A1 as potential cancer biomarkers.

A randomized clinical trial on the antitumoral effects of low molecular weight heparin in the treatment of esophageal cancer.

The current treatment approaches for esophageal cancer are associated with poor survival, and there are ongoing efforts to find new and more effective therapeutic strategies. There are several reports on the antitumoral effects of low-molecular-weight heparins (LMWHs). We have assessed the possible survival benefit of LMWHs in esophageal malignancies. This was a randomized, single-blind, multicenter, Phase II clinical trial on nonmetastatic esophageal cancer candidate for neoadjuvant chemoradiotherapy. Patients were randomly assigned to the chemoradiotherapy-only arm or chemoradiotherapy plus enoxaparin arm using 1:1 allocation. Radiotherapy was delivered in 1.8-Gy daily fractions to a dose of 50.4 Gy in both groups. Paclitaxel 50 mg/m2 and carboplatin (AUC 2) were administered weekly, concurrent with radiotherapy. In the intervention group, patients received enoxaparin (40 mg) and chemoradiation daily. 4-6 weeks after treatment, all patients underwent esophagectomy. After a median follow up of 7 months, estimated 1 year disease-free survival (DFS) in the intervention group was 78.9% and was 70% in the control groups ( p = 0.5). Toxicity from the experimental treatment was minimal, and there were no treatment-related deaths. A pathologically complete response in intervention and control group was 64.8% and 62.5%, respectively ( p = 0.9). There was a nonsignificant trend toward improved survival by the addition of enoxaparin to the concurrent chemoradiotherapy regimen. However, 1 y DFS of both groups were high as expected. A longer follow-up and a larger sample size are required.

Therapeutic potential of targeting the Wnt/ß-catenin pathway in the treatment of pancreatic cancer.

The Wnt/ß-catenin pathway is an important, dysregulated pathway in several tumor types, including pancreatic ductal adenocarcinoma. Although the activation of this pathway is an important component of normal development, its aberrant activation resulting from activating or inactivating mutations in the CTNNB1 gene locus, or in the negative regulators AXIN and APC involving stabilization of ß-catenin, and activation of target genes leads to a more aggressive phenotype, suggesting its potential value as a therapeutic target in the treatment of pancreatic ductal adenocarcinoma. A number of small molecule and biologic agents have now been developed for targeting this pathway. This review summarizes the current knowledge about the therapeutic potential of targeting the Wnt pathway with particular emphasis on preclinical/clinical studies in the treatment of pancreatic ductal adenocarcinoma.

Anti-tumoral effects of low molecular weight heparins: A focus on the treatment of esophageal cancer.

Esophageal cancer is one of the most prevalent types of cancer globally. With current treatment options, the survival is poor, and there are ongoing efforts to find new and more efficient therapeutic approaches. There are several reports on the anti-tumoral effects of low-molecular-weight heparins (LMWH). We have assessed the possible survival benefits and underlying mechanisms of LMWHs in malignancies with a focus on esophageal cancer. We conclude that the effects of LMWHs on survival of cancer patients is probably due to a combination of direct anti-tumoral, anti-angiogenic, and immunomodulatory effects and indirect effects on the coagulation system.

Outcomes of Induction Chemotherapy Followed by Chemoradiotherapy Versus Chemoradiotherapy Alone in Esophageal Squamous Cell Carcinoma Induction chemotherapy in Esophageal Squamous Cell Carcinoma.

BACKGROUND: There is still no definite conclusion regarding the effect of Induction Chemotherapy (IC) combined with concurrent Chemoradiotherapy (CRT). Thus this study was aimed to assess outcomes of IC followed By CRT versus CRT alone in Esophageal Squamous Cell Carcinoma (ESCC). METHODS: This multicenter retrospective study performed on 105 patients who underwent CRT and 73 patients who underwent IC+CRT, between January 2016 and December 2018. The primary endpoints were OS (from the date of treatment to the date of death or 3- years follow-Up). The toxicities of CRT were graded according to the National Cancer Institute Common Toxicity Criteria (version 3.0). RESULTS: one-year (73.8% vs. 53.2%) and 2-year (53.4% vs. 38.5%) OS rate of the IC+CRT group was significantly higher than that of the CRT group (p < 0.05). No statistically significant differences were observed between the IC+CRT group and the CRT group (31.5% vs. 27.4%) in terms of the 3-year OS rate (p > 0.05). In multivariate logistic regression, age<60 (OR: 1.48; CI 95% 1.02-1.97), clinical staging II (OR: 1.36; CI 95% 1.11-1.88), and the addition of IC (OR: 1.66; CI 95% 1.07-2.19) were independent prognostic factors that affected survival positively. CONCLUSION: Our data demonstrated that a combination of IC and CRT might be a promising treatment strategy to further improve OS in ESCC patients.

Extended dosing (12 cycles) vs conventional dosing (6 cycles) of adjuvant temozolomide in adults with newly diagnosed high-grade gliomas: a randomized, single-blind, two-arm, parallel-group controlled trial.

Purpose: Maximum safe surgical resection followed by adjuvant chemoradiation and temozolomide chemotherapy is the current standard of care in the management of newly diagnosed high grade glioma. However, there are controversies about the optimal number of adjuvant temozolomide cycles. This study aimed to compare the survival benefits of 12 cycles against 6 cycles of adjuvant temozolomide adults with newly diagnosed high grade gliomas. Methods: Adult patients with newly diagnosed high grade gliomas, and a Karnofsky performance status>60%, were randomized to receive either 6 cycles or 12 cycles of adjuvant temozolomide. Patients were followed-up for assessment of overall survival (OS) and progression-free survival (PFS) by brain MRI every 3 months within the first year after treatment and then every six months. Results: A total of 100 patients (6 cycles, 50; 12 cycles, 50) were entered. The rate of treatment completion in 6 cycles and 12 cycles groups were 91.3% and 55.1%, respectively. With a median follow-up of 26 months, the 12-, 24-, 36-, and 48-month OS rates in 6 cycles and 12 cycles groups were 81.3% vs 78.8%, 58.3% vs 49.8%, 47.6% vs 34.1%, and 47.6% vs 31.5%, respectively (p-value=.19). Median OS of 6 cycles and 12 cycles groups were 35 months (95% confidence interval (CI), 11.0 to 58.9) and 23 months (95%CI, 16.9 to 29.0). The 12-, 24-, 36-, and 48- month PFS rates in 6 cycles and 12 cycles groups were 70.8% vs 56.9%, 39.5% and 32.7%, 27.1% vs 28.8%, and 21.1% vs 28.8%, respectively (p=.88). The Median PFS of 6 cycles and 12 cycles groups was 18 months (95% CI, 14.8 to 21.1) and 16 (95% CI, 11.0 to 20.9) months. Conclusion: Patients with newly diagnosed high grade gliomas treated with adjuvant temozolomide after maximum safe surgical resection and adjuvant chemoradiation do not benefit from extended adjuvant temozolomide beyond 6 cycles. Trial registration: Prospectively registered with the Iranian Registry of Clinical Trials: IRCT20160706028815N3. Date registered: 18/03/14.

Outcome of Second Line Treatment of Recurrent High- Grade Glioma by re-Irradiation or Bevacizumab-based Chemotherapy: A Cross Sectional Study.

INTRODUCTION: Currently, there is no standard of treatment for the management of the recurrent high-grade glioma. Re-resection, re-irradiation, and chemotherapy are among main treatment options without any proven efficacy. AIM: To compare the outcome of second line treatment of recurrent high-grade glioma by re-irradiation or bevacizumab-based chemotherapy. METHODS: Retrospectively, patients with the recurrent high-grade glioma treated by re-irradiation (ReRT group) (34 patients) or bevacizumab-based chemotherapy (Bev group) (40 patients) as the first-file after the first recurrence were compared in term of first-line progression free survival (PFS), second-line PFS, and overall survival (OS). RESULTS: Both groups were similar in term of gender (p=0.859), age (=0.071), type of first-line treatment (p=0.227), and performance status (p=0.150). With a median follow-up of 31 months (m), mortality rate was 41.2% and 70% in the ReRT and Bev groups, respectively. In the Bev and ReRT groups, median OS was 27 m (95% confidence interval (CI) 20-33.9 m) vs. 132 m (95% CI 52.9-211 m) (p<0.0001), median first-line PFS was 11 m (95% CI 7.14-28.7 m) vs. 37 m (95% CI 8.42-65.75 m) (p<0.0001), and median second-line PFS was 7 m (95% CI 3.9-10 m) vs. 9 m (95% CI 5.5-12.4 m) (p=0.564), respectively. CONCLUSION: The PFS is similar after the second line treatment of recurrent primary central nervous system malignancies either by re-irradiation or bevacizumab-based chemotherapy.

Total Neoadjuvant vs. Standard Perioperative Cisplatin/ Doxorubicin Chemotherapy in Patients with Extremities Osteosarcoma: A Multi-Center Cohort Study.

INTRODUCTION: Despite improvements in survival of patients with high-grade osteosarcoma after the implementation of perioperative chemotherapy, osteosarcoma remains among the most lethal cancers. Prescription of all chemotherapy courses before the surgery may provide this opportunity to eliminate micrometastases more efficiently, increase the chances of pathologic complete response and organ preserving surgery. This study aimed to compare the outcomes of total neoadjuvant chemotherapy vs. standard perioperative chemotherapy with cisplatin/doxorubicin regimen in patients with extremities osteosarcoma. METHODS: In this retrospective cohort, all patients with high-grade osteosarcoma admitted to oncologic centers affiliated to Iran University of Medical Sciences in Tehran, Iran from 2015 to 2021 were included. Organ preserving rates, pathologic responses, and survival of patients who received all six courses of cisplatin/doxorubicin regimen preoperatively were compared to those who received the regimen perioperatively. RESULTS: Sixty-three patients were enrolled (total neoadjuvant chemotherapy: 32 patients and perioperative chemotherapy: 31 patients). In total neoadjuvant chemotherapy and perioperative chemotherapy groups, favorable pathology responses (necrosis>90%) were reported in 80.6% and 15.6% of patients, respectively (p<0.001). With a median follow-up of 24 months, mean overall survival of total neoadjuvant chemotherapy and perioperative chemotherapy groups were 21.29 months (95% CI; 19.3-23.27) and 23.46 months (95% CI; 22.7-24.1), respectively (p=0.2). The mean disease-free survival of patients in total neoadjuvant chemotherapy and perioperative chemotherapy groups were 19.54 months (95% CI; 17.0-22.0) and 21.37 months (95% CI; 19.4-23.2), respectively (p=0.2). CONCLUSION: Our results showed that prescription of all courses of doxorubicin/cisplatin chemotherapy prior to surgery can increase favorable pathologic response rates, although this improvement is not translated into overall and disease-free survival benefits.
