“…first demonstrated the clinicopathological features of an extremely rare case of primary mucinous adenocarcinoma arising in the renal pelvis . Following that, a substantial number of interesting case reports describing the pathological features of primary pelvic adenocarcinoma were published; however, within our thorough investigation, we found less than 100 cases reported in the English literature, with most cases reported from Asian countries . Indeed, it is well‐known that transitional cell (urothelial) carcinoma accounts for up to 90% of epithelial‐origin malignancies arising from the renal pelvis, whereas adenocarcinoma accounts for less than 1% .…”

Primary adenocarcinoma of the upper tract urothelial cell carcinomas (UTUCs) is rarely reported. We report a case of primary adenocarcinoma of the ureter with elevated carbohydrate antigen 19-9 (CA-19-9). A 44-year-old male was admitted to the hospital for severe right flank and hypogastrium pain for 7 days without visible or microscopic haematuria. The patient underwent radical nephroureterectomy followed by chemotherapy with gemcitabine/ carboplatin and inorelbine/Adriamycin (ADM)/5-fluoro-2,4 (1 h, 3 h) pyrimidinedione (5-FU) and radiotherapy, and the level of CA19-9 decreased to normal. Histopathology revealed adenocarcinoma. The patient died of tumor pelvic metastasis after 6 months. A review of the literature is also reported.

“…Among non‐UCs, SQ is much more rare, with just 1.3–6% of UUTC being SQ 8,9 . The proportions of AC and SmC are approximately 1% and <0.5%, respectively 10,11 . Due to the rarity of non‐UC of the UUT, limited information is available regarding its prognosis.…”

ObjectivesTo identify the prognosis of patients with non‐urothelial carcinoma of the upper urinary tract and compare it with that of patients with urothelial carcinoma.MethodsWe used hospital‐based cancer registry data in Japan to extract histologically confirmed non‐urothelial carcinoma and urothelial carcinoma cases of the upper urinary tract diagnosed in 2008–2009. We estimated the 5‐year overall survival by a Kaplan–Meier analysis. The Cox proportional hazards regression analysis was used to evaluate prognostic factors.ResultsA total of 2567 upper urinary tract cancer patients with confirmed histological subtypes were identified. The most common histology of non‐urothelial carcinoma was squamous cell carcinoma (n = 88, 3.4%) followed by adenocarcinoma (n = 33, 1.3%) and small cell carcinoma (n = 10, 0.4%). The proportion of advanced stage in the squamous cell carcinoma patients was significantly higher than that in the urothelial carcinoma patients (P = 0.003). In stage IV, the proportion of patients who received a combination of surgery + chemotherapy in the urothelial carcinoma group was higher than that in the non‐urothelial carcinoma group (34% vs 16%, respectively). The 5‐year overall survival rates of the non‐urothelial carcinoma patients at stages I–III and stage IV were significantly worse than those of the urothelial carcinoma patients (P = 0.003, P < 0.001, respectively). In multivariate analyses, age ≥73 years, advanced stage (stage IV), tumor location (ureter) and the presence of non‐urothelial carcinoma histology were independent poor prognosis factors.ConclusionThe prognosis of non‐urothelial carcinoma patients is worse than that of urothelial carcinoma patients, especially for non‐urothelial carcinoma patients at stage IV. More effective systemic therapies are required to improve these patients’ oncological outcomes.
