It is the second leadingcause of cancer death in both men and women in the United States and over one-third of newly diagnosed patients have stage Ⅲ(node-positive) disease. For stage Ⅱ and Ⅲ colorectal cancer patients, the mainstay of curative therapy is neoadjuvant therapy, followed by radical surgical resection of the rectum. However, the consequences of a proctectomy, either by low anterior resection or abdominoperineal resection, can lead to very extensive comorbidities, such as the need for a permanent colostomy, fecal incontinence, sexual and urinary dysfunction, and even mortality. Recently, trends of complete regression of the rectal cancer after neoadjuvant chemoradiation therapy have been confirmed by clinical and radiographic evaluationthis is known as complete clinical response(cC R). The "watch and wait" approach was first proposed by Dr. Angelita Habr-Gama in Brazil in 2009. Those patients with c CR are followed with close surveillance physical examinations, endoscopy, and imaging. Here, we review management of rectal cancer, the development of the "watch and wait" approach and its outcomes.展开更多

Questionnaires(20 questions on education background, previous AOM experience, knowledge on antimicrobial resistance and attitude vs the WW approach) were filled by 600 parents(150 at each centers) of children < 6 years of age.RESULTS: Mothers represented 69% of parents; 2% had an education of < 10 school years, 46% had high-school education and 17% had an academic degree. 69% parents reported previous experience with AOM and 56% thought that antibiotics represent the only treatment for AOM. Knowledge on bacterial resistance to antibiotics was reported by 57% of the parents; 86% parents were willing to accept/probably accept the WW approach for their children. Logistic regression analysis revealed a significant association between parental education and knowledge about bacterial resistance to antibiotics and that previous experience with AOM was significantly associated with reluctance to accept the WW approach. More parents with knowledge on bacterial resistance were willing to accept the WW approach compared with parents without such knowledge. No correlation was found between the education level and willingness to accept the WW approach. CONCLUSION: A significant correlation was found between previous parental education and experience with AOM and the knowledge about antibiotic use, bacterial resistance and acceptance of the WW approach.展开更多

The clinical course of NENs is quite heterogeneous, with different spontaneous growth rates after diagnosis, and different degrees of sensitivity to the same therapy even when they have similar characteristics. Watch and wait(W and W), is a term coined to indicate observation being conducted to assess the evolution of the tumor without administering any anti-tumor therapy. It has been applied to NENs since in extremely rare cases they tend to remain stable for a long time. Although W and W has been reported in several guidelines and recommendations it has never been validated, nor has it been specifically investigated. Furthermore it is not standardized. Therefore its application in clinical practice can differ in terms of tumor status assessment, type and timing of imaging or other exams utilized. In conclusion, while undertaking W and W to delay the first-line therapy by some weeks may be justified in good performance asymptomatic patients with low-grade NENs in order to usefully characterize the disease and patient and thereby choose the best therapy and therapeutic strategy, it seems to be far more difficult to justify W and W with the intent of avoiding an anti-tumor treatment. It should be considered that not only do NENs tend to grow even when they have very favorable biological characteristics but also that the alternative to W and W is most commonly a low toxic and effective treatment with somatostatin analogs.展开更多
