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...

Triple negative breast cancer (TNBC) is the most aggressive form of breast cancer with limited options of targeted therapy. Recent findings suggest that the clinical course of TNBC may be modified by the presence of tumor-infiltrating lymphocytes (TILs) and chemokine's expression, such as CCL5. Diverse studies have shown that CCL5 suppresses anti-tumor immunity and it has been related to poor outcome in different types of cancer while in other studies, this gene has been related with a better outcome. We sought to determine the association of CCL5 with the recruitment of TILs and other immune cells...

PURPOSE: To determine, in a retrospective analysis of a large cohort of stage III non-small cell lung cancer patients treated with curative intent at our institution, whether having a pathologic complete response (pCR) influenced overall survival (OS) or freedom from recurrence (FFR) in patients who underwent definitive (≥60 Gy) neoadjuvant doses of chemoradiation (CRT). METHODS AND MATERIALS: At our institution, 355 patients with locally advanced non-small cell lung cancer were treated with curative intent with definitive CRT (January 2000-December 2013), of whom 111 underwent mediastinal reassessment for possible surgical resection...

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...

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...

Automated breast ultrasonography (ABUS) is a new imaging technology for automatic breast scanning through ultrasound. It was first developed to overcome the limitation of operator dependency and lack of standardization and reproducibility of handheld ultrasound. ABUS provides a three-dimensional representation of breast tissue and allows images reformatting in three planes, and the generated coronal plane has been suggested to improve diagnostic accuracy. This technique has been first used in the screening setting to improve breast cancer detection, especially in mammographically dense breasts...

Neoadjuvant therapy (NAT) for oesophageal cancer may reduce cardiopulmonary function, assessed by cardiopulmonary exercise testing (CPEX). Impaired cardiopulmonary function is associated with mortality following esophagectomy. We sought to assess the impact of NAT on cardiopulmonary function using CPEX and assessing the clinical relevance of any change in particular if changes were associated with post-operative morbidity. This was a prospective, cohort study of 40 patients in whom CPEX was performed before and after NAT...

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...

BACKGROUND: At present, intrahepatic cholangiocarcinoma is a contraindication for liver transplantation. However, previous studies in this field did not preselect patients on the basis of chemosensitivity or disease trajectory after neoadjuvant therapy. Experience with hilar cholangiocarcinoma has indicated that neoadjuvant therapy followed by liver transplantation in patients without disease progression results in a long-term survival benefit. We aimed to establish the potential efficacy of liver transplantation in patients with biologically responsive intrahepatic cholangiocarcinoma who have had sustained tumour stability or regression with neoadjuvant therapy...

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+)...

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...

Objective: Stage N2-3 nasopharyngeal carcinoma (NPC) shows a high risk of distant metastasis, which will finally cause death. This study aimed to evaluate the impact of neoadjuvant chemotherapy (NACT) of various cycles before radical radiotherapy on distant metastasis and survival of patients with stage N2-3 diseases. Methods: In this study, a total of 1,164 consecutive patients with non-metastatic N2-3 NPC were recruited and prospectively observed. Then 231 patients who received NACT of 4 cycles (NACT=4 group) were matched 1:2:1 to 462 patients treated with NACT of 2 cycles (NACT=2 group) and 231 patients treated without NACT (NACT=0 group), according to age, histological subtype, N stage and NACT regimen...
