To the Editor,

The presence of concomitant co-existing ma­lignancies has been accepted since the report of Warren and Gates. [1] Such occurrences raise the possibility of mutations such as the Beck­with-wiedemann syndrome or certain etiologi­cal factors like alcohol and/or smoking. [2],[3] The patient's follow-up might be altered under these circumstances.

In a study done by Ray and colleagues on patients with multiple primary malignancies, genito-urinary tumors were identified in 12.5% of the patients. [4] In this study, we present a pa­tient with concomitant kidney and sigmoid malignancies.

The patient was a 68-year-old female with history of hematochezia of eight months dura­tion. A colonoscopy was performed which re­vealed a polypoid lesion located about 20 cm above the anal sphincter. Pathologic examina­tion of biopsy of the lesion, showed evidence of adenocarcinoma. The patient underwent re­section of the lesion with free margins fo­llowed by colonic anastomosis. Three months after this event, the patient presented with gross hematuria, which needed two units of blood transfusion. A CT-scan of the abdomen and pelvis with intravenous contrast was then per­formed, which demonstrated the presence of a heterogenous mass in the left kidney. The pa­tient then underwent left radical nephrectomy with probable diagnosis of metastasis. The pathology report, however, showed renal cell carcinoma (RCC) of the left kidney.

The concomitant presence of RCC with other primary malignancies including cancers of bla­dder, prostate, colorectum, lung, malignant me­lanoma (MM) of skin and non-Hodgkin's lym­phoma has been reported. [5],[6],[7],[8],[9] Rabbani et al re­ported that 209 patients out of 763 patients (27.4%) with RCC had another primary cancer, of whom, 104 cases (39.2%) were concomi­tant. Fourteen of these patients from the above­mentioned figure had concomitant colorectal cancers. [10] Beisland et al reported that 287 pa­tients out of 1425 had another primary cancer, and that 53 of them were concomitant. Of them, 25 out of 287 had colonic cancer, and 14 others had rectal cancer. [11]

Rabbani also reported that there was no sig­nificant relationship between RCC and colo­rectal cancer. [10] Although the probability of the presence of tumor in other organs was higher in patients with RCC, the incidence of colo­rectal cancers in these patients was not higher than the control group. [7],[11] Higher incidence was seen only in patients with bladder cancer. [10]

Sato and colleagues have studied survival rate in malignancies seen concomitantly with RCC. [12] According to their report, presence of other primary tumors concomitant with RCC (at the time of nepherectomy) is an independent pre­dictive factor for postoperative survival rate. Furthermore, patients with localized RCC (T 1-2) and concomitant malignancy had lower survival rate than those with localized RCC (T 1-2) only. Hemminki and Czene showed higher risk of cancer within the first year after diag­nosis and also after 10 years of diagnosis time (6%). Follow-up of RCC is usually performed for five years after surgery. [13]

Based on all these studies, we recommend that after completion of the routine follow-up course following surgery for malignancy, the patient should be examined every two years to look for evidence of any other malignancies.
