==MAP==
MAP: High-dose Methotrexate, Adriamycin (Doxorubicin), Platinol (Cisplatin)
===Regimen variant #1===
Study 	Dates of enrollment	Evidence 	Comparator 	Comparative Efficacy
Bramwell et al. 1992	1983-1986 	Phase 3 (E-esc)	Cisplatin & Doxorubicin	Seems to have shorter DFS
Note: The body of Bramwell et al. 1992 says that methotrexate is given over 4 hours, whereas Bramwell et al. 1992 figure 1's text says that methotrexate is given over 6 hours.
====Chemotherapy====
*Methotrexate (MTX) 8000 mg/m2 IV over 4 to 6 hours once on day 1
*Doxorubicin (Adriamycin) 25 mg/m2 IV bolus once per day on days 11 to 13
*Cisplatin (Platinol) 100 mg/m2 IV continuous infusion over 24 hours, started on day 11
====Supportive therapy====
*Leucovorin (Folinic acid) 12 mg/m2 IV every 6 hours x 10 doses or 15 mg/m2 PO every 6 hours x 10 doses, starting 24 hours after the start of methotrexate infusion
**Monitor methotrexate level at "24 hours and 48 hours"--it is unclear in the reference if this is time after the start/end of methotrexate, beginning of leucovorin, or something else
**Methotrexate levels higher than 100 nmol/L at 48 hours required additional leucovorin rescue
*Prehydration for methotrexate: "0.9 NaCl:D5W"--unclear if this means either normal saline or D5W can be used--750 mL/m2 over 6 hours, with KCl 20 mEq/L
*The volume of fluid for methotrexate is D5W 1000 mL, to be given over 6 hours
*Posthydration for methotrexate: Alternating liters of D5W and NS 3000 mL/m2 over 24 hours, with KCl 60 mEq/L.
*Sodium bicarbonate 3 g PO Q6H, starting 12 hours before methotrexate, and sodium bicarbonate 167 mmol/L IV until serum methotrexate level is less than 8000 to 10,000 nmol/L. Note: the reference is not clear about when/if PO sodium bicarbonate is stopped, when IV sodium bicarbonate is started, or the administration rate of IV sodium bicarbonate.
*Prehydration for cisplatin: normal saline 400 mL/m2 and D5W 400 mL/m2 IV over 2 hours--the reference did not clarify if these two solutions are given at the same time
*The volume of fluid for cisplatin continuous infusion is 2400 mL/m2 NS, with KCl 80 mEq/L and mannitol 32,000 mg/m2
*Posthydration for cisplatin: D5W 600 mL/m2 over 6 hours, with KCl 20 mEq/L and mannitol 8000 mg/m2; and NS 600 mL/m2 over 6 hours, with KCl 20 mEq/L, magnesium sulfate 2 mmol/L, and calcium gluconate 0.6 mmol/L--the reference did not clarify if these two solutions are given at the same time. Then D5W 600 mL/m2 over 12 hours, with KCl 20 mEq/L and mannitol 8000 mg/m2.
*Furosemide (Lasix) 20 to 40 mg IV if urine output is less than 400 mL/m2 over 6 hours during cisplatin
21-day cycle for 2 cycles
====Subsequent treatment====
*Definitive surgery on week 9, then adjuvant MAP that starts 14 to 28 days after surgery
===Regimen variant #2===
Study 	Dates of enrollment	Evidence
Bacci et al. 1993 (IOR/OS-2)	1986-09 to 1989-12 	Phase 2
====Chemotherapy====
*Methotrexate (MTX) 8000 mg/m2 IV over 6 hours once on day 1
*Doxorubicin (Adriamycin) 60 mg/m2 IV over 8 hours once on day 9, starting 48 hours after the start of cisplatin
*Cisplatin (Platinol) 40 mg/m2/day IA continuous infusion over 72 hours, started on day 7 (total dose per cycle: 120 mg/m2)
====Supportive therapy====

====Subsequent treatment====
*Definitive surgery, then risk-adapted therapy. Amputated patients restart chemotherapy 3 to 5 days after surgery; patients who undergo limb salvage or rotation plasty restart chemotherapy 10 to 21 days after surgery.
**IOR/OS-2, at least 90% tumor necrosis in the surgically removed specimen: Adjuvant MAP
**IOR/OS-2, less than 90% tumor necrosis in the surgically removed specimen: Adjuvant MAPIE
===Regimen variant #3===
Study 	Dates of enrollment	Evidence 	Comparator	Comparative Efficacy
Winkler et al. 1988 (COSS-82)	1982-1984 	Phase 3 (E-switch-ic)	M-BCD 	Higher ORR
Note: The exact schedule is unclear based on limited information in the reference, as schedule of doses is primarily extrapolated from Figure 1, which does not contain clear delineations in time. The dose/schedule of cisplatin reflects the protocol amendment that was done because of nephrotoxicity.
====Chemotherapy====
*Methotrexate (MTX) 12,000 mg/m2 (maximum dose of 20,000 mg) IV over 4 hours once per day on days 22 & 29
**MTX is dissolved at a concentration of 20,000 mg/L in a solution containing 5% glucose
*Doxorubicin (Adriamycin) 30 mg/m2 IV bolus once per day on days 1 & 2
*Cisplatin (Platinol) 90 mg/m2 IV over 4 hours once on day 3
====Supportive therapy====
*Leucovorin (Folinic acid) 15 mg/m2 PO every 6 hours x 12 hours once per day on days 23 & 30, starting 24 hours after the completion of methotrexate infusion; additional leucovorin used for delayed methotrexate elimination
*Sodium bicarbonate urine alkalinization prior to high-dose methotrexate
*NS 4.5 L/m2 on day 1 after methotrexate; NS 3 L/m2 on day 2, with adjustments made to keep urine pH greater than 7.4
*12 hours of hydration prior to cisplatin & 20 hours of hydration after cisplatin; total amount of fluid given over 36hours of prehydration, cisplatin, and posthydration is NS 6 L/m2 with mannitol 8 g/L and potassium 20 mval/L.
*Magnesium 180 mg/m2 PO "per day throughout the whole chemotherapy time"--as described in COSS-80
35-day cycle for 2 cycles
====Subsequent treatment====
*Surgery, then risk-adapted treatment:
**COSS-82, good response: Adjuvant MAP
**COSS-82, poor response: Adjuvant IP-BCD
===Regimen variant #4===
Study 	Dates of enrollment	Evidence 	Comparator	Comparative Efficacy
Winkler et al. 1984 (COSS-80)	1979-1982 	Phase 3 (E-switch-ic)	MA-BCD 	Did not meet primary endpoint of CDF rate
Note: The exact schedule is unclear based on limited/conflicting information in the reference. For example, Figure 1 appears to depict high-dose methotrexate starting 2 weeks after adriamycin, but the text says that methotrexate begins after a 3-week rest period. Additionally, the diagram in Figure 1 implies that the later therapies are given 4 times (once, then repeated x 3 cycles), but based on the cumulative doses listed, they are only given for a total of 3 cycles. The optional interferon arm is omitted given lack of benefit seen in the study.
====Chemotherapy====
*Methotrexate (MTX) as follows:
**Cycle 1: 12,000 mg/m2 (maximum dose of 20,000 mg) IV over 4 hours once per day on days 29 & 36
**Cycles 2 to 4: 12,000 mg/m2 (maximum dose of 20,000 mg) IV over 4 hours once per day on days 1, 8, 29, 36
**MTX is dissolved at a concentration of 20,000 mg/L in a solution containing 5% glucose
*Doxorubicin (Adriamycin) as follows:
**Cycles 1, 3, 4: 45 mg/m2 IV bolus once per day on days 1 & 2
**Cycle 2: 45 mg/m2 IV bolus once per day on days 15 & 16 (delayed during cycle 2 until after surgery)
*Cisplatin (Platinol) 120 mg/m2 IV over 5 hours once on day 43
====Supportive therapy====
*Leucovorin (Folinic acid) 15 mg/m2 PO every 6 hours x 12 hours once per day on days 2, 9, 30, 37, starting 24 hours after the completion of methotrexate infusion; additional leucovorin used for delayed methotrexate elimination
*Sodium bicarbonate urine alkalinization prior to high-dose methotrexate
*NS 4.5 L/m2 on day 1 after methotrexate; NS 3 L/m2 on day 2, with adjustments made to keep urine pH greater than 7.4
*3 hours of hydration prior to cisplatin & 3 hours of hydration after cisplatin; total amount of fluid given over 11 hours of prehydration, cisplatin, and posthydration is NS 2.5 L/m2 with mannitol 8 g/L and potassium 20 mval/L.
*Magnesium 180 mg/m2 PO "per day throughout the whole chemotherapy time" with cisplatin
8-week cycle for 4 cycles, with surgery done during cycle 2 before doxorubicin; surgery is done 9 to 18 weeks after the start of chemotherapy
