Concurrent chemoradiotherapy (CRT)

- Radiotherapy 25 ㏉/5 fractions (start concomitantly at D1)

- ↓ ↓ ↓ ↓ ↓

- Radical surgery 6 weeks after completion of chemoradiotherapy

- ↑ ↑ ↑ ↑ ↑ D1 - - - - - D5

- 5-Fluorouracil 400㎎/㎡/day + LV 20㎎/㎡/day IV bolus during the radiotherapy


Radiotherapy using tomotherapy is delivered in 5 Gy daily fractions for a total of 25 Gy in 5 fractions.

A bolus injection of 5-fluorouracil (400 mg/m2/d)and leucovorin (20 mg/m2/d) is delivered concurrently on day 1-5 during radiotherapy.

Total mesorectal excision is performed within 6±2 weeks. The pathological response of downstaing is the study endpoint.

Short-course Radiotherapy (5×6Gy/7Gy/8Gy) Followed by Neo-adjuvant Chemotherapy for Locally Advanced Rectal Cancer

Preoperative radiotherapy followed by total mesorectal excision (TME) has been recommended as the preferred treatment method for locally advanced rectal cancer. Similar rates of local cont...

The Stockholm III Trial on Different Preoperative Radiotherapy Regimens in Rectal Cancer

There are theoretical reasons to believe that radiotherapy (RT) given in larger fractions during a shorter period of time might result in more late side effects than giving a conventional,...

Preoperative Chemoradiation Versus Short Term Radiation Alone With Delayed Surgery for Stage II and III Resectable Rectal Cancer

Trial compares two preoperative stage II and III rectal cancer treatment strategies: short term radiotherapy 5x5 Gy and delayed surgery after 6 weeks versus conventional chemoradiotherapy ...

The Randomised Study of Preoperative Radiotherapy With Consolidating Chemotherapy for Unresectable Rectal Cancer

The addition of Oxaliplatin to conventionally fractionated chemoradiation (FULV or capecitabine) is considered as standard in unresectable rectal cancer by the panel of experts. The Invest...

Short Course Radiation Therapy Followed by Pre-operative Chemotherapy and Surgery in High-risk Rectal Cancer

Adjuvant Chemotherapy in Rectal Cancer Patients Treated with Preoperative Chemoradiation and Total Mesorectal Excision: A Multicenter and Retrospective Propensity-Score Matching Study.

The role of adjuvant chemotherapy after preoperative chemoradiotherapy (CRT) and curative surgery in rectal cancer has not to be definitely determined yet. We performed a retrospective and multicenter...

miR-21, miR-99b and miR-375 combination as predictive response signature for preoperative chemoradiotherapy in rectal cancer.

Preoperative chemoradiotherapy (CRT) is a standard treatment for locally advanced rectal cancer patients. Despite the benefits of CRT, its use in non-responder patients can be associated with increase...

Phase I and II trial on infusional 5-fluorouracil and gefitinib in combination with preoperative radiotherapy in rectal cancer: 10-years median follow-up.

The aim of this study is to evaluate the long term survival of the addition of gefitinib to chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC).

Clinical Impact of Preoperative Albumin-Globulin Ratio in Patients with Rectal Cancer Treated with Preoperative Chemoradiotherapy.

The serum albumin-globulin ratio (AGR) is associated with malignancy outcomes. However, among patients with rectal cancer (RC) who undergo neoadjuvant chemoradiotherapy (nCRT), the clinical and progno...

Prognostic impact of doublecortin-like kinase 1 expression in locally advanced rectal cancer treated with preoperative chemoradiotherapy.

Preoperative chemoradiotherapy (CRT) is a standard therapy for locally advanced rectal cancer; however, the response varies depending on cases. Therefore, CRT-response predictors need to be elucidated...

Medical and Biotech [MESH] Definitions

Short-lived elementary particles found in cosmic radiation or produced from nuclear disintegration. Their mass is between that of protons and electrons and they can be negative, positive, or neutral. pi-Mesons (pions) are heavier than mu-mesons (muons) and are proposed for cancer radiotherapy because their capture and disintegration by matter produces powerful, but short-lived, secondary radiation.

Combined chemotherapy and radiotherapy given to augment some other form of treatment such as surgery. It is commonly used in the therapy of cancer.

Tumors or cancer of the RECTUM.

Electromagnetic or corpuscular radiation capable of producing ions, directly or indirectly, in its passage through matter. The wavelengths are equal to or smaller than those of short (far) ultraviolet radiation and include gamma and X-rays and high-energy elementary particles.

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
