According to patient’s statement, his presenting complaints started 1.5 months back. Then he noticed streaks of blood on stool admixed with mucus. He also complained of alteration of bowel habit with early morning diarrhea and increased frequency of defecation (10times/day). He had been experiencing sense of incomplete defecation for the last 1.5 months. He developed pain on the central lower abdomen for the last 7 days which was stretching in nature and was aggravated by filling of urinary bladder and relieved by micturition. The patient was anorexic and lost 50% of his previous body weight. He gave no history of jaundice, ascites, hematuria, hemoptysis, melena. The patient was not diabetic, normotensive. He was a chain smoker, smoking 25 sticks per day for 40 years. He came from low socio-economic status and none of the member of his family suffered from such disease. On general examination, the patient was ill looking, of average body built, malnourished, co-operative and decubitus on choice. He was anemic, dehydrated, not icteric, not edematous. His pulse, blood pressure, temperature and respiratory rate were within the normal limits. Neck vein was not engorged, neck gland was not enlarged, peripheral lymph nodes were not palpable, hernial orifices were intact. On abdominal examination, mild tenderness was found in lower abdomen. No organomegaly was found. On digital rectal examination, there was no visible excoriation, fecal soiling, hemorrhoids, fissure or fistula. On palpation, anal tone was normal. There was a circumferential mass, located 5 cm above the anal verge. It was hard in consistency, surface was irregular and fixed with surrounding structures. Upper limit of the mass could not be reached. On withdrawal , the finger was blood stained. Other systemic examination revealed no abnormality. Provisional diagnosis: Carcinoma rectum Differential diagnosis: i. Intestinal tuberculosis ii. Hemorrhoids Investigation: • For diagnosis: Proctoscopy with biopsy. • To see extension: Colonoscopy (to exclude synchronous tumour) • To see metastasis: Chest X-ray P/A view USG whole abdomen Liver function test CT scan of chest and abdomen • For pre-operative staging: Endoluminal USG of rectum (to assess local spread) MRI (for local staging) Endoluminal USG of rectum • G/A fitness: CBC Urine R/M/E Random blood glucose Serum creatinine Chest X-ray P/A view ECG Confirmatory diagnosis: Carcinoma rectum. Management: A. Preoperative preparation: • Counseling and siting of stomas • Correction of anemia and electrolyte disturbance • Cross matching of blood • Bowel preparation • Prophylactic antibiotics • Insertion of urinary catheter B. Surgery: • Curative treatment: Anterior resection Carcinoma Rectum Definition: Carcinoma located within 12cm of the anal verge by rigid proctoscopy is called carcinoma rectum. [National Comprehensive Cancer Network Guideline (UK)] Risk Factors: Age above 50years Male gender High intake of fat Alcoholism & smoking High intake of red meat Obesity Person with family history of 2 or more 1st degree relative has 2 to 3 fold greater risk factor. Accumulation of genetic abnormalities Increase in dysplasia in adenoma Adenocarcinoma [adenoma-carcinoma sequence] Low grade • Well differentiated • Prognosis is good Average grade • Moderately differentiated • Prognosis is fair High grade • Undifferentiated • Prognosis is poor H & E stain: Rectal carcinoma Dukes’ Staging A Limited to rectal wall B C D Extension to extra rectal tissue C1: Pararectal lymph nodes involved C2: Lymph nodes accompanying vessels involved Widespread metastasis TNM Staging • T1 : Tumor invasion through muscularis mucosa. • T2 : Tumor invasion into muscularis propria • T3 : Tumor invasion through the muscularis propria but not through the serosa • T4 : Tumor invasion through the serosa or esorectal fascia • N0 : No lymph node involvement • N1 : Between 1 and 3 involved lymph nodes • N2 : 4 or more involved lymph nodes • M0 : No distant metastasis • M1 : Distant metastasis Types of rectal carcinoma spread 1. Local spread: Circumferential spread rather than in a longitudinal direction. 2. Lymphatic spread: It occurs almost exclusively in an upward direction. 3. Venous spread: Principal sites of metastasis are, Liver (34%) Lungs(22%) Adrenal gland (11%) Other organs (33%) 4. Peritoneal dissemination: It occurs in case of high lying rectal carcinoma. •More common in developed countries. •Higher rates in Australia New Zealand Europe USA. •Lower rate in South Central Asia , Africa. •More common in men. Principles of surgical treatment: • Curative treatment • Palliative treatment Curative treatment: Even in the presence of widespread metastasis a rectal excision should be considered. • Tumor whose lower margin is ≥2 cm above the anal canal: Anterior resection (sphincter saving operation): Temporary colostomy is done. • Tumor in upper 1/3rd of rectum or rectosigmoid tumor: High Anterior Resection • Tumor involving the lower 1/3rd of the rectum: SCAPR (Synchronized Combined Abdominoperineal Resection): Permanent sigmoid end colostomy is done. • Tumor involving middle & lower 1/3rd : TME (Total mesorectal excision) • Others: TEM (Trans anal Endoscopic Microsurgery): In case of unfit patients & small low grade T1 tumor. Hartmann’s operation: for old and frail patient. Palliative treatment: • Radiotherapy: Preoperative radiotherapy can be given for inoperable primary tumor or local recurrence, especially when painful. • Chemotherapy: Adjuvant chemotherapy can improve survival in node positive diseases. • Combined radiotherapy & chemotherapy can be given to shrink an extensive tumor prior to surgical excision. • Palliative colostomy When there is intestinal obstruction. When there is gross infiltration of neoplasm.
