— What is Rectal Cancer?

Understanding Rectal Cancer

Rectal cancer is a malignant tumour arising in the rectum, the final 15 to 20 centimetres of the large intestine before the anus. Although closely related to colon cancer, rectal cancer has distinct features in its presentation, staging, and treatment, particularly the critical role of MRI staging and the possibility of organ preservation in selected cases.

Mr Kumar has advanced training in the management of rectal cancer, having completed specialist fellowships at two of Europe’s leading centres. He specialises in robotic TME, which offers superior precision in the confined space of the pelvis and is associated with better functional and oncological outcomes.

Mr Kumar offers the full range of modern treatments including organ preservation strategies and transanal approaches. He avoids a stoma wherever it is surgically safe to do so, and discusses all options frankly with each patient so they can make a fully informed decision about their care.

Early Rectal Cancer

Early Stage (T1–T2)

Confined to the rectal wall. Local excision (TAMIS) may be curative for very early lesions. Radical surgery (TME) for T2 disease and above.

Locally Advanced

Locally Advanced (T3–T4)

Extending through the rectal wall or involving adjacent structures. Pre-operative chemoradiotherapy followed by surgery is the standard approach.

Symptoms

🔴

Rectal Bleeding

Bright red blood mixed with or coating the stool. The most common presenting symptom of rectal cancer. Always requires investigation in adults over 40.

💩

Change in Bowel Habit

Increased frequency, loose stools, urgency, or a feeling of incomplete evacuation (tenesmus), particularly new symptoms persisting for more than 3 weeks.

🚫

Feeling of Incomplete Emptying

A persistent sensation that the bowel has not fully emptied after defaecation, a classic symptom of a rectal mass.

Unexplained Weight Loss

Unintentional weight loss is a red flag symptom that should always prompt urgent investigation.

😴

Fatigue and Anaemia

Iron deficiency anaemia from chronic blood loss, presenting with tiredness, pallor and breathlessness.

Pelvic or Perineal Pain

Pain in the pelvis or perineum may indicate locally advanced disease involving surrounding structures.

⚕ Clinical Note

Rectal bleeding should never be assumed to be due to haemorrhoids without proper assessment in adults over 40. Prompt specialist evaluation is essential to exclude malignancy.

— Diagnosis and Staging

Investigation Pathway

1

Colonoscopy and Biopsy

Full colonoscopic assessment of the rectum and colon to identify the tumour, obtain biopsy for histological diagnosis, and exclude synchronous lesions.

2

MRI of the Rectum

High-resolution MRI is the gold standard for local staging of rectal cancer. It defines the relationship of the tumour to the mesorectal fascia (circumferential resection margin), guides surgical planning and identifies who needs pre-operative treatment.

3

CT Chest, Abdomen and Pelvis

Systemic staging to identify lymph node involvement and distant metastases.

4

MDT Review

All cases are discussed by the colorectal cancer multidisciplinary team, including surgeons, oncologists, radiologists and pathologists, before treatment commences.

— Treatment Options

Management Pathway

1

Local Excision (TAMIS)

For very early rectal cancer · Organ-preserving · Day case
  • What is TAMIS? Transanal Minimally Invasive Surgery uses a specialised platform inserted through the anus to excise early rectal tumours under direct vision, avoiding the need for major abdominal surgery.
  • Who is Suitable? Selected early tumours with favourable histological features. Requires careful pre-operative MRI and endoscopic assessment.
  • Recovery Day case or overnight stay. Return to normal activities within 1 week.
TAMIS preserves the rectum entirely and avoids major surgery for carefully selected early rectal cancers, an approach not available at all centres.
2

Robotic Total Mesorectal Excision (TME)

The gold standard for rectal cancer surgery
  • What is TME? Total Mesorectal Excision is the complete removal of the rectum together with its surrounding mesorectal envelope, containing the draining lymph nodes. It is the standard curative procedure for rectal cancer.
  • Why Robotic? The robotic platform is ideally suited to the narrow confines of the pelvis. It provides superior 3D visualisation, greater instrument range of motion, and more precise nerve preservation, reducing the risk of bladder and sexual dysfunction.
  • Anterior Resection vs APE High and mid rectal tumours are treated by anterior resection (bowel joined back together). Low rectal tumours may require abdominoperineal excision (APE) with a permanent stoma when the sphincter cannot be preserved.
Mr Kumar specialises in robotic TME. The robotic approach achieves equivalent oncological outcomes to open surgery with significantly better functional recovery and lower complication rates.

Pre-operative Chemoradiotherapy

For locally advanced rectal cancer
  • Who Needs It? Locally advanced (T3/T4) tumours, or those where the MRI shows threatened surgical margins, are treated with pre-operative chemoradiotherapy to downstage the tumour before surgery.
  • Short-Course Radiotherapy 5 fractions of radiotherapy over one week for selected tumours not requiring downstaging. Surgery is performed shortly after.
  • Watch and Wait In exceptional cases where the tumour has a complete clinical response to chemoradiotherapy, a non-operative Watch and Wait strategy with intensive surveillance may be appropriate, avoiding surgery entirely.
The decision on pre-operative treatment is made by the MDT based on MRI staging. Mr Kumar works closely with the oncology team to ensure each patient receives optimal pre-operative and post-operative care.

— Follow-Up and Surveillance

After Treatment

After curative treatment for rectal cancer, close surveillance is maintained for at least 5 years. This includes:

🔬

CEA Monitoring

Blood CEA measured every 3 to 6 months for 3 years as a marker of recurrence.

📷

CT Surveillance

Annual CT chest, abdomen and pelvis for 3 to 5 years.

🔭

Endoscopic Surveillance

Flexible sigmoidoscopy or colonoscopy at regular intervals to assess the anastomosis and detect local recurrence or metachronous polyps.
