Aim of this study is to review our experience in the management of patients with synchronous and metachronous lesions, and reach conclusions regarding their optimal diagnosis, treatment and follow-up. Patients and methods: Between and , 12 patients seven men and five women, mean age The diagnosis lag for metachronous lesions ranged from 1. All three patients with synchronous cancers had two lesions. Results: Staging colonoscopy and abdominal CT was conducted in 10 patients while the remaining two underwent only abdominal CT due to their critical condition at presentation. Surgery had curative intent in 10 patients and palliative in two. The mean postoperative hospital stay was 21 days 10 - 49 days. The postoperative mortality was zero. Conclusions: Patients with colorectal cancer must be followed up regularly after surgery. Follow up aims at early diagnosis and treatment of metachronous lesions that can appear many years after diagnosis of the primary lesion. Preoperative colonoscopy is an invaluable diagnostic biopsy and staging exclusion of synchronous lesions, localization of the primary modality, dictating the surgical approach. Additionally, it contributes to cancer prevention allowing the discovery and removal of small polyps before their transformation. Multiple primary carcinomas often occur in the rectum and colon.

Metrics details. The situation of patients developing multiple primary cancers is becoming more frequent and graver. This study investigated the risks of developing second primary cancers that are related to first primary cancers, and the interval times of synchronous and metachronous multiple primary cancers. A two-month period between first- and second- primary cancers was used to differentiate metachronous and synchronous multiple primary cancers. The combinations of subsequent cancers and relative risks RRs of having multiple primary cancers versus having single primary cancer for the top-ten first and second primary cancers were examined.

Purpose: Patients with spinal metastases SM from solid neoplasms typically exhibit progression to an advanced cancer stage. Such metastases can either develop concurrently with an existing cancer diagnosis termed metachronous SM or emerge as the initial indication of an undiagnosed malignancy referred to as synchronous SM. The present study investigates the prognostic implications of synchronous compared to metachronous SM following surgical resection.
