3.Criteria and definitionsused in this study

3.1.Clinical staging

Staging before enrollment should be performed according to the staging classification of 1992 version of JSOG (Japan Society of Obstetrics and Gynecology), 1988 version of Federation of Gynecology and Obstetrics (FIGO) and 2002version of American Joint Committee on Cancer (AJCC).Although staging of ovarian cancer is originally surgical staging, following classification will be applied taking account of clinical information such as imaging study, physical examination, and cytological diagnosis.Stage should be classified as lower category when it wavers in judgement.

3.1.1.Ovarian cancer

Stage ITumor limited to the ovaries.

Stage IITumor involving one or both ovaries with pelvic extension.

Stage IIITumor involving one or both ovaries with intraperitoneal metastases outside the pelvis and/or positive retroperitoneal lymph nodes.

IIIaMicroscopic disease in the upper abdomen.

IIIbMetastases smaller than 2 cm in the upper abdomen.

IIIcMetastases larger than 2 cm in the upper abdomen.

Stage IVTumor involving one or both ovaries with distant metastases outside the upper abdomen or intrahepatic metastases.

3.1.2.Tubal cancer

Staging of tubal cancer should be performed according to the classification of 1991 version of FIGO.The definitions of stage III/IV disease are same as above described definition for ovarian cancer.

3.1.3.Peritoneal cancer

Staging of stage III/IV peritoneal cancer is performed according to the classification for ovarian cancer, thereforedefinition of extra-pelvic metastases and distant metastases in each stage are same as those for ovarian cancer.

3.2.Classification of epithelial stromal tumor of ovarian cancer

Histological classification of 1990 version of Japan Society of Obstetrics and Gynecology and The Japanese Society of Pathology is applied for the histological classification of ovarian cancer.Subjects of this study are following tumors other than underlinedtumors.

1)Serous tumors

  • Adenocarcinoma
  • Surface papillary adenocarcinoma
  • Adenocarcinofibroma

2)Mucinous tumors、endocervical、intestinal and mixed types

  • Adenocarcinoma
  • Adenocarcinofibroma

3)Endometrioid tumors

  • Adenocarcinoma
  • Adenocarcinofibroma
  • Adenosarcoma
  • Mesodermal mixed tumor、Carcinosarcoma
  • Stromal sarcoma

4)Clear cell tumors

  • Adenocarcinoma
  • Adenocarcinofibroma

5)Brenner tumors

6)Transitional cell carcinoma

7)Mixed epithelial tumors

8)Undifferentiated carcinoma

9)Unclassified

For the histological classification of tubal cancer or peritoneal cancer, above histological classification for ovarian cancer is also applied.

3.3.Definition for surgical debulking

Optimal surgery in PDS (primary debulking surgery) and IDS (interval debulking surgery): Regardless of removed tumor volume or range of surgery, debulking surgery leaving residual tumors less than 1cm in diameter of maximum residual tumor at the completion of debulking surgery is classified as optimal surgery and no less than 1cm classified as suboptimal surgery.

3.4.Calvertformula

Dose of Carboplatin (CBDCA) should be calculated using following Calvert formula

Dose (mg) = Planned AUC (mg/ml・min) x (GFR(ml/min) + 25)

3.5.Cockcroft-Gault formula

Creatinine clearance should be calculated using following Cockcroft-Gault formula

Ccr(ml/min) =0.85 x / (140-Age) x Body Weight(Kg)
72 x Serum Cr(mg/dl)

6.Protocol treatment and criteria for treatment modification

Treatment and modification of treatment should be performed according to the description of this section, as far as safety of the patients is not threatened.

Treatment should be modified according to the judgment by physicians in charge when it is medically danger to follow the protocol.Though, in that case the modification may be “protocol deviation”, it should be considered as “clinically appropriate protocol deviation” when it is judged as medically appropriate (refer section “14.1.3. “).It should not be considered as “clinically appropriate protocol deviation” when the deviation is performed with the intension of improving the efficacy.

6.1.Protocol treatment

6.1.1.Treatment plan

Treatment for arm A and Bareset to upfront surgery arm and neoadjuvant chemotherapy arm, respectively.Thoughpatients should be hospitalized for each chemotherapy cycle as a rule, chemotherapy in outpatients’ clinic is allowed in both treatment arms.

“6.3.1. Criteria for starting a cycle of chemotherapy” is not applied for a first cycle of chemotherapy in arm B.

I.Arm A (Upfront surgery arm)

Patients are treated with PDS followed by 4cycles of post-operative chemotherapy, IDS if eligible (refer “6.1.3.II.) and additional 4 cycles of post-operative chemotherapy.

1)PDS should be performed within 28 days after enrollment.Reasons should be recorded in the “Case report form for courses of treatment” when PDS is postponed until29th day or later after enrollment.“Case report form for end of treatment” should be recorded as discontinuation of protocol treatment when PDS cannot be performed.To start protocol treatment or not is depend on the judge of physicians in charge when clinical laboratory data and so on become worse not to satisfy eligibility criteria after enrollment.

2)Post-operative (PDS) chemotherapy should be started within 21 days after PDS when only uterus, adnexa, omentum and peritoneum are removed during PDS.Chemotherapy should be started within 35 days after PDS when any other organs are removed during PDS.Before the initiation of chemotherapy, it should be confirmed that criteria for starting a cycle of chemotherapy is fulfilled.

3)IDS should be performed from 28thday to 49th day after 4th cycle of post-operative chemotherapy when eligibility criteria for IDS are fulfilled during 21st day to 49th day.Even if PDS resulted in suboptimal surgery, the 5th cycle of post-operative chemotherapy can be started from 21st day or later after 4th cycle of chemotherapy when physicians in charge decide it is not necessary to perform IDS.

4)Post-operative (IDS) chemotherapy should be started within 21 days after IDS when only uterus, adnexa, omentum and peritoneum are removed during IDS.Chemotherapy should be started within 35 days after IDS when any other organs are removed during IDS.In either case, number of chemotherapy is 4 cycles after IDS and 8 cycles in total.Before the initiation of chemotherapy, it should be confirmed that criteria for starting a cycle of chemotherapy is fulfilled.

II.Arm B (Neoadjuvant chemotherapy arm)

Patients are treated with 4 cycles of neoadjuvant chemotherapy, followed by IDS and 4cycles of post-operative chemotherapy.

1)NAC should be started within 14 days after enrollment.Reasons should be recorded in the “Case report form for courses of treatment” when NAC is postponed until 15th day or later after enrollment.“Case report form for end of treatment” should be recorded as discontinuation of protocol treatment when NAC cannot be started.To start protocol treatment or not is depend on the judge of physicians in charge when laboratory data and so on become worse not to satisfy eligibility criteria after enrollment.

2)IDS should be performed from 28th day to 49th day after 4th cycle of NAC when eligibility criteria for IDS are fulfilled during 21st day to 49th day.

3)Post-operative (IDS) chemotherapy should be started within 21 days after IDS when only uterus, adnexa, omentum and peritoneum are removed during IDS.Chemotherapy should be started within 35 days after IDS when any other organs are removed during IDS.In either case, number of chemotherapy is 4 cycles after IDS and 8 cycles in total.Before the initiation of chemotherapy, it should be confirmed that criteria for starting a cycle of chemotherapy is fulfilled.

JCOG0602 ver.1.3

6.1.2.Chemotherapy

TC regimen will be administered 8cycles intotal every 3 weeks in both A and B arms.It should be confirmed that criteria for starting a cycle of chemotherapy is fulfilled except for first cycle in arm B.Paclitaxel is intravenously administered in 3 hours followed by intravenous administration of Carboplatin.

Drug / Dose / Rout / Date
Paclitaxel / 175 mg/m2 / div(3 hr) / day 1
Carboplatin / AUC 6 / div(1 hr) / day 1
I.Paclitaxel(PTX)

1)Body surface area to calculate dose of PTX is based on body weight (BW) at entry for 1st to 4th cycles of chemotherapy or BW before 5th cycle of chemotherapy for 5th to 8th cycles of chemotherapy.Dose is determined by discarding fractions less than 5mg. (c.f. 124mg is rounded off to 120mg.)

2)Dose modification due to a change of BW should not be performed at startingany other cycles of chemotherapy.

3)It is recommended to administerdexamethasone, diphenhydramine and ranitidine as premedication before administration of `PTX to protect anaphylactic reactions.

4)Dexamethasone is administered once at 30 min before administration of PTX for practical convenience.
