Adenocarcinoma of the caecum metastatic to the bladder: an unusual cause of haematuria
BACKGROUND: Primary malignancies of colorectal origin can metastasise to the bladder. Reports are however extremely rare, particularly from the caecum. CASE REPORT: The report describes the case of a 45-year old male with Duke's B caecal carcinoma treated with a laparoscopically-assisted right hemicolectomy and adjuvant 5-Fluorouracil chemotherapy. Subsequently, a metastatic lesion to the bladder was demonstrated and successfully excised by partial cystectomy. CONCLUSION: In order that optimal therapeutic options can be determined, it is important for clinicians to distinguish between primary disease of the bladder and other causes of haematuria. Various immunohistochemical techniques attempt to differentiate primary adenocarcinoma of the bladder from secondary colorectal adenocarcinoma. Suspicion of metastatic disease must be raised when histologically unusual bladder tumours are identified
A case of relapsing secondary bladder adenocarcinoma after right colonic cancer
Background A 71-year-old woman was referred to a surgical oncology clinic after CT raised suspicion for a bladder neoplasm. She had previously undergone right hemicolectomy and received adjuvant chemotherapy for pT3N1MX cancer of the cecum. A retroperitoneal recurrence had been deemed unsuitable for surgical resection, and had instead been treated with chemoradiation therapy. Follow-up CT raised suspicion for a possible bladder neoplasm. Investigations CT, physical examination, urinalysis, cystoscopy with biopsy, pathological analysis and immunohistochemical analysis. Diagnosis Adenocarcinoma of the cecum metastatic to the bladder. Management The patient underwent open bladder resection with total excision of the neoplasm and was administered adjuvant chemotherapy consisting of irinotecan and cetuximab. Subsequent recurrences at the same site were treated with transurethral resection, while chemotherapy was still in progress. At 7 months' follow-up, the patient remained alive, with no evidence of further recurrence

Powering membrane traffic in endocytosis and recycling
Early in evolution, the diversification of membrane-bound compartments that characterize eukaryotic cells was accompanied by the elaboration of molecular machineries that mediate intercompartmental communication and deliver materials to specific destinations. Molecular motors that move on tracks of actin filaments or microtubules mediate the movement of organelles and transport between compartments. The subjects of this review are the motors that power the transport steps along the endocytic and recycling pathways, their modes of attachment to cargo and their regulation
