Neoadjuvant therapy has become the standard of care for locally advanced mid-low rectal cancer. Pathological complete response (pCR) can be achieved in 12%-38% of patients. Patients with pCR have the most favorable long-term outcomes. Intensifying neoadjuvant therapy and extending the interval between termination of neoadjuvant treatment and surgery may increase the pCR rate. Growing evidence h...

The majority of patients with operable esophageal cancers present with locally advanced disease, for which surgical resection as a sole treatment modality has been historically associated with poor survival. Even following radical resection, most of these patients will eventually succumb to their disease due to distant metastasis. For this reason, there has been intense interest in the role of ...

Neoadjuvant therapy may provide advantages to some women with primary operable breast cancer. Compared to the administration of the same regimen in the adjuvant setting, neoadjuvant chemotherapy does not improve survival outcomes, but may provide other benefits. Neoadjuvant therapy is associated with improved rates of breast-conserving therapy, may offer prognostic information, and enables asse...

Background. Since neoadjuvant treatment in esophageal cancer began to become popular, a complete pathological response at the primary tumour site has been commonly reported. An issue of conflict is whether complete response in the esophageal lumen means that the esophagus is completely tumour-free. Another important issue is whether lymph nodes that are retrieved from pathologically complete re...

OBJECTIVE The purpose of this study was to determine whether preoperative neoadjuvant therapy in patients with locally advanced pancreatic cancer affects the ability of multiphasic MDCT to predict successful surgical resection. MATERIALS AND METHODS From 2000 to 2006, there were 12 patients with prior neoadjuvant therapy successfully downstaged by CT and 31 age-matched pancreatic cancer patie...

The use of neoadjuvant chemotherapy or radiation for borderline resectable pancreatic adenocarcinoma (BL-PDAC) is increasing. However, the impact of neoadjuvant chemotherapy and radiation therapy on the outcome of BL-PDAC remains to be elucidated. We performed a retrospective analysis of 93 consecutive patients who were diagnosed with BL-PDAC and primarily followed at Johns Hopkins Hospital bet...

Radical prostatectomy is the effective treatment for clinical T2 prostatic cancer. However, clinical T2 stage is often understaged preoperatively. The objective of neoadjuvant therapy is to increase the curability of surgery to understaged patients. The present study was based on patients who had had neoadjuvant endocrine therapy (LH-RH agonist) prior to radical nerve-sparing prostatectomy for ...

The indolent nature of estrogen-dependent breast cancer is the most important obstacle for development of new adjuvant endocrine treatments. Clinical trials require thousands of study participants and at least a decade of clinical investigation. How can we be sure that a new endocrine agent warrants this extraordinary level of investment? Traditionally, we have relied on advanced breast cancer ...

Neoadjuvant (preoperative) systemic therapy is a good possibility for the treatment of symptomatic breast cancers of the locoregional stage. Chemotherapy or hormone therapy chosen according to the characteristics of the primary tumor, result in the regression of the tumor in the majority of the cases, favoring breast conserving surgery thereafter. The long-term effects of neoadjuvant systemic t...
