Neuronal calcium sensor-1 (NCS-1) has been identified as a binding partner of the taxane, paclitaxel. Our previous study showed that overexpression of NCS-1 increased the efficacy of paclitaxel in vitro, but was associated with poor clinical outcome. Here, we determine if NCS-1 expression is associated with pathological complete response (pCR) to taxane-based neoadjuvant chemotherapy in 105 pre-treatment breast cancer biopsies. Elevated expression of NCS-1 was found to be positively associated with pCR. These results suggest that NCS-1 may be a predictive biomarker for response to taxane-based neoadjuvant chemotherapy in breast cancer...

Effective treatment of advanced metastatic disease remains the primary challenge in the management of inoperable pancreatic cancer. Current therapies such as oxaliplatin (OxPt)-based chemotherapy regimens (FOLFIRINOX) provide modest short-term survival improvements, yet with significant toxicity. Photodynamic therapy (PDT), a light-activated cancer therapy, demonstrated clinical promise for pancreatic cancer treatment and enhances conventional chemotherapies with non-overlapping toxicities. This study investigates the capacity of neoadjuvant PDT using a clinically-approved photosensitizer, benzoporphyrin derivative (BPD, verteporfin), to enhance OxPt efficacy in metastatic pancreatic cancer...

BACKGROUND: Currently, one of the most used strategies for the treatment of newly diagnosed patients with breast cancer is neoadjuvant chemotherapy based on the application of taxanes and anthracyclines. However, despite the high number of patients who develop a complete pathological clinical response, resistance and relapse following this therapy continue to be a clinical challenge. As a component of the innate immune system, the cytotoxic function of Natural Killer (NK) cells plays an important role in the elimination of tumor cells...

BACKGROUND AND PURPOSE: Current prognostic models for soft tissue sarcoma (STS) patients are solely based on staging information. Treatment-related data have not been included to date. Including such information, however, could help to improve these models. MATERIALS AND METHODS: A single-center retrospective cohort of 136 STS patients treated with radiotherapy (RT) was analyzed for patients' characteristics, staging information, and treatment-related data. Therapeutic imaging studies and pathology reports of neoadjuvantly treated patients were analyzed for signs of response...

The aim of the present study was to assess the immediate and long-term results of preoperative brachytherapy and chemotherapy followed by radical surgery compared with those of standard chemoirradiation in patients with stage IB2-IIA cervical cancer. The medical records of 70 patients with stage IB2 and IIA cervical cancer who were treated between June 2006 and June 2010 were reviewed. The patients received either standard chemoirradiation (CRT) treatment (n=20) or neoadjuvant brachytherapy with one cycle of chemotherapy followed by radical hysterectomy [operation (OT) group; n=50]...

The standard treatment for locally advanced uterine cervical cancer is concurrent chemoradiotherapy. Successful neoadjuvant chemotherapy (NAC) may reduce tumor size and facilitate a hysterectomy, thereby improving the prognosis for patients with locally advanced cervical cancer. In contrast, unsuccessful NAC may worsen the prognosis because if a hysterectomy is not possible, the change in treatment plan may delay the initiation of core treatment. Therefore, there is a need to identify biomarkers that predict the efficacy of NAC in patients with uterine cervical cancer...

The most widely accepted treatment for cutaneous angiosarcoma (CAS) is wide local excision and postoperative radiation to decrease the risk of recurrence. Positive surgical margins and large tumors (T2, >5 cm) are known to be associated with poor prognosis. Moreover, T2 tumors are known to be associated with positive surgical margins. According to previous reports, the majority of CAS patients in Japan had T2 tumors, whereas less than half of the patients in the studies from western countries did so. Consequently, the reported 5-year overall survival of Japanese CAS patients without distant metastasis was only 9%, lower than that for stage-IV melanoma...

To evaluate the importance of MRI texture analysis in prediction and early assessment of treatment response before and early neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced rectal cancer (LARC). This retrospective study comprised of 59 patients. The tumoral texture parameters were compared between pre- and early nCRT. Area Under receiver operating characteristic (ROC) Curves [AUCs] were used to compare the diagnostic performance of statistically significant difference parameters and logistic regression analysis predicted probabilities for discriminating responders and nonresponders...

BACKGROUND: Radiotherapy has long been the treatment of choice for local control of Ewing sarcoma of the chest wall (ESCW). However, there is debate regarding the use of surgery versus RT. Our objective was to identify risk factors that may affect long-term outcomes of non-metastatic ESCW all treated with preoperative chemotherapy followed by en-bloc resection and adjuvant Chemotherapy or Chemoradiation. METHODS: Between 1996 and 2014, 30 patients with a median age of 25 years (SD +/-8...

BACKGROUND: The 8th edition of the AJCC TNM staging system presents for the first time a specific classification for esophageal carcinomas treated with neoadjuvant therapy (yTNM8). In this single center study, we applied the novel staging system in a "real life" case series and compared the prognostic value of yTNM8 with the preceding 7th edition (TNM7). METHODS: Out of 272 consecutive esophageal carcinomas that were treated during a 15-year period in one surgical center, all 198 cases that had undergone neoadjuvant therapy were reviewed and classified according to TNM7 and yTNM8...

BACKGROUND: Radical cystectomy (RC) is delayed in a subset of patients who respond poorly to neoadjuvant chemotherapy (NAC). The present study investigated the clinicopathologic characteristics predicting extravesical disease at RC and the factors associated with NAC tolerability to improve patient selection and the sequence of definitive therapy. MATERIALS AND METHODS: Patients with cT2 urothelial carcinoma of the bladder who underwent NAC were stratified by the final pathologic stage: complete (ypT0N0), partial (≤ pT2), and nonresponse (> pT2 and/or N+)...

OBJECTIVE: Definitive chemoradiotherapy (CRT) remains the most commonly used treatment for locally advanced esophageal squamous cell carcinoma (SCC), because of perceptions that esophagectomy offers an unclear survival advantage. We compare recurrence, overall survival (OS), and disease-free survival (DFS) in patients treated with definitive CRT or neoadjuvant CRT followed by surgery (trimodality). METHODS: This was a retrospective cohort study of patients with stage II and III SCC of the middle and distal esophagus in patients who completed CRT...

Advancements in rectal cancer treatment have resulted in improvement only in locoregional control and have failed to address distant relapse, which is the predominant mode of treatment failure in rectal cancer. As the efficacy of conventional chemoradiotherapy (CRT) followed by total mesorectal excision (TME) reaches a plateau, the need for alternative strategies in locally advanced rectal cancer (LARC) has grown in relevance. Several novel strategies have been conceptualized to address this issue, including: 1) neoadjuvant induction and consolidation chemotherapy before CRT; 2) neoadjuvant chemotherapy alone to avoid the sequelae of radiation; and 3) nonoperative management for patients who achieved pathological or clinical complete response after CRT...

BACKGROUND: Recently there are efforts to use sentinel lymph node biopsy (SLNB) techniques after neoadjuvant chemotherapy (NAC) to minimize axillary surgery. However, studies have shown higher false negative rates in this scenario, which might result in inaccurate assessment of treatment response and patient prognosis as well as leaving residual disease behind. In this study, we describe the use of reflector-guided excision of the percutaneously biopsied node (PBN) as an aid to conventional SLNB and its predictor of the axillary status after NAC...

BACKGROUND: Ewing sarcoma/primitive neuroectodermal tumor is a family of highly malignant proliferation of neuroectodermal origin, most often skeletal, adrenal localization is extremely rare. Only few cases have been reported in the literature. Classical management includes radical surgery with adjuvant chemotherapy or radiotherapy or both. This case report is the only one where recurrence was surgically removed, and it confirms the importance of adjuvant treatment, and the efficacy of neoadjuvant chemotherapy...

Introduction Esophageal and esophago-gastric junction (EGJ) adenocarcinomas remain a major health problem worldwide with a worryingly increasing incidence. Recent trials indicate survivals benefit for preoperative or perioperative chemoradiotherapy compared to surgery alone. Beside standard chemoradiotherapy regimens, new therapeutic approaches with targeted therapies have been proposed for the treatment of resectable disease. However, clinical outcomes remain extremely poor due to drug resistance phenomena...
