A Study Of Moderately Hypo-Fractionated External-beam Radiotherapy With Concurrent Chemotherapy and High Dose Rate Brachytherapy In Cervical Cancer

Summary

Cancer of the uterine cervix is one of the most common gynecologic cancer diagnosis and cause of death among gynecologic cancers worldwide .The two major histologic types of cervical cancer are squamous cell carcinoma, adenocarcinoma and the preinvasive disease that corresponds with these histologies share many of the same risk factors . Cancer cervix can be treated definitively with concurrent chemoradiation (external beam radiotherapy and chemotherapy) followed by high dose rate brachytherapy. Treatment duration can be shortened by increasing the dose per fraction of treatment, which can improve survival rates, reduce the risk of treatment failure, reduce costs and patient exposure.

Eligibility

Inclusion Criteria:

1. Age 18 years or older.
2. International Federation of Gynecology and Obstetrics (FIGO) IB1 cervical cancers if not surgical candidates, but amenable to definitive chemoradiotherapy.
3. FIGO Stage IB2, IB3, IIA or IIB cervical cancers
4. FIGO stage IIIA, IIIB.
5. FIGO stage IIIC1 cervical cancers are candidates but must meet all the following criteria (to avoid extented field technique ): The largest radiologically suspicious positive pelvic node is less than 3 cm. Less than 3 radiologically suspicious positive nodes. No suspicious nodes located in the common iliac chain.
6. Histologically-confirmed invasive uterine cervical carcinoma of subtypes squamous cell, adenocarcinoma or adenosquamous cell.
7. Candidate for definitive chemoradiotherapy to be delivered with weekly cisplatin (Creatinine clearance more than 60 ml/min). Carboplatin AUC 2 is acceptable alternative if cisplatin is not tolerated (creatinine clearance 40:60 ml/min) .
8. Brachytherapy candidate.
9. Eastern Cooperative Oncology Group (ECOG) performance status up to 2 .

Exclusion Criteria:

* 1.FIGO stage IA, IIIC2, IVA or IVB. 2.FIGO stage IIIC1 with node is equal or greater than 3 cm, common iliac node or greater than 2 radiologically suspicious nodes.

  3.Previous pelvic or abdominal radiotherapy. 4.Active inflammatory bowel disease. 5.Active connective tissue disorder (eg. scleroderma, systemic lupus erythematous).

  6.Patient unable to undergo MR scan 7.Eastern Cooperative Oncology Group (ECOG) performance status equal to 3 or more.

  8.Creatinine clearance less than 40 ml/min.
