Background: Colorectal cancer (CRC) is a common malignancyworldwide and its outcome is most closely related to the extent of disease at presentation. Early diagnosis of an asymptomatic recurrence increases the likelihood of a complete surgical resection.

Objectives: The aim of this study was to evaluate the incidence of colorectal cancer recurrence and survival rate within 5 years, after surgery.

Patients And Methods: During the 9-year period since 21st Mar, 2004 to 20th Mar, 2013, patients whose primary colorectal cancer were resected in Taleghani hospital, Tehran, Iran were selected in a historical cohort. The necessary data such as demographic, age, gender, family history of CRC, site and size of tumor, stage of tumor, operation details, histological results, treatment method, histopathologic, etc. were collected. Then the recurrence and survival of colorectal cancer within 5 years after operation and their risk factors were evaluated. P value less than 0.05 were considered significant. All analysis was done using SPSS software.

Results: A total of 107 patients underwent resection for colorectal cancer during the study period, with mean age of 53.50 ± 12.68 years (range 24 - 76 years), survival rate of 73.8% (rectum 70.0% and colon 75.9%), and mean survival time of 142.17 ± 21.60 month. The recurrence rate of CRC patients, during five years after surgery was 5.7%. Regional lymph nodes, Distance metastasis and Adjuvant therapy were significant prognosis factors of survival after surgery.

Conclusions: The rate of recurrence in Iranian patients was low, which could be due to improvement of exactness and expertise of surgeons or better adjuvant therapy. The significant association between survival and adjuvant therapy clarifies this finding. Early diagnosis and primary detection could increase the rate of survival.

QT intervals in patients receiving a renal transplant.

Exp Clin Transplant 2012 Apr;10(2):105-9

Objectives: Cardiovascular disease is the most-common cause of mortality in patients with end-stage renal disease and renal transplant. Prolongation of QTc(max) and QTc dispersion are risk factors of cardiac arrhythmias and mortality. This study compares the changes of QT parameters before hemodialysis, after hemodialysis, and after renal transplant.

Materials And Methods: Patient candidates for renal transplant were selected. Mean serum electrolyte and 12-lead electrocardiogram were recorded (1) immediately, (2) before and, (3) after the last dialysis session before renal transplant, (4) and 2 weeks after a kidney transplant in 34 patients with normal graft function (plasma Cr ≤ 176.8 μmol/L). Each QT interval was corrected for the patient's heart rate using Bazett's formula. The QT parameters (QTd, QTcd, QTc(max)) were compared between prehemodialysis, posthemodialysis, and 2 weeks after renal transplant using a paired t test and a general liner model repeated measure. The correlation between QT parameter changes and serum electrolyte and acidbase alternation was analyzed.

Results: The corrected maximal QT interval (QTc(max)) decreased significantly after successful renal transplant compared to prehemodialysis (P = .002) and posthemodialysis (P = .003) with a paired t test and a General Liner Model Repeated Measure (P < .001) between the 3 groups. Also, the mean of QTc(max) decreased significantly after renal transplant (P = .001) compared to what it was before hemodialysis and after hemodialysis. There was a significant correlation (r= -0.37) between reduction of QTc(max) and serum Ca level (P = .01) in postrenal transplant period.

Conclusions: Renal transplant with normal graft function decrease QTc(max) compared to prehemodialysis and posthemodialysis that may correlate with normalization of electrolytes from the uremic state of the normal kidney function.
