Gemcitabine and cisplatin

Gemcitabine and cisplatin is a two medicine chemotherapy plan used for bladder cancer and several other cancers, given on days 1 and 8 of a 3 week cycle.

Also called: GC, Gem-Cis, GemCis, gem cis, cisplatin and gemcitabine, CisGem, gemcitabine cisplatin, Gem-Cis with durvalumab, Gem-Cis with pembrolizumab, Gem-Cis with nivolumab, gem-carbo, gemcitabine and carboplatin

What it is

Gemcitabine and cisplatin damage cancer cells in different ways, and they work better together. Before bladder surgery, the goal is to shrink the cancer and lower the chance it comes back. When cancer has spread, the goal is to shrink it, slow it down and help you live longer and feel better. For some cancers, an immunotherapy medicine is added to help your immune system fight the cancer.

Often used for

Before bladder surgery (neoadjuvant)
Usually 4 cycles before the bladder is removed. Some people also get durvalumab with the chemotherapy and then for several months after surgery.
Bladder cancer that has spread
Usually 4 to 6 cycles. If the cancer shrinks or stays the same, avelumab is often started afterward to help keep it in check. Gem-cis with nivolumab is another option. Your team may also talk with you about other first treatments, such as enfortumab vedotin with pembrolizumab.
Biliary tract cancer with durvalumab or pembrolizumab
Gem-cis plus an immunotherapy medicine, every 21 days. Cisplatin is usually stopped after about 8 cycles, and the immunotherapy (sometimes with gemcitabine) continues as long as it is helping.
Gem-carbo (gemcitabine and carboplatin)
Used when cisplatin is not safe, for example because of weak kidneys, hearing loss, nerve damage, heart failure or low energy. Carboplatin is easier on the kidneys and hearing but tends to lower blood counts more.
Nasopharyngeal cancer
Gem-cis may be given for a few cycles before chemotherapy with radiation, or for cancer that has spread, often with an immunotherapy medicine.

The medicines in this plan

Gemcitabine
Chemotherapy that stops cancer cells from copying their DNA. Given through a vein over about 30 minutes on day 1 and day 8.
Cisplatin
Platinum chemotherapy. Given through a vein with extra IV fluids, usually on day 1 (some centers split it over days 1 and 8). It is the medicine that can affect the kidneys and hearing.
Carboplatin
Only in the gem-carbo version. A platinum chemotherapy that is easier on the kidneys and hearing, used in place of cisplatin when cisplatin is not safe.
Durvalumab
Only in some versions. An immunotherapy medicine given through a vein on day 1, used with gem-cis for biliary tract cancer and, in some cases, before and after bladder surgery.
Pembrolizumab
Only in some versions. An immunotherapy medicine given through a vein on day 1, used with gem-cis for biliary tract cancer.
Nivolumab
Only in some versions. An immunotherapy medicine that may be added for bladder cancer that has spread.
Avelumab
Not given with the chemotherapy. An immunotherapy medicine that may be started after gem-cis for bladder cancer that has spread, to help keep the cancer under control (maintenance).

How you get it

Gem-cis is given in an outpatient infusion clinic through a vein or a port (a small device placed under the skin of the chest). Day 1 takes about 4 to 6 hours because cisplatin needs IV fluids before and after it. Day 8 is shorter, about 1 to 2 hours. Each cycle is 21 days. Before bladder surgery, most people get 4 cycles; for cancer that has spread, usually 4 to 6 cycles. Your schedule may be different.

A typical cycle

Day 1
Blood tests, including kidney tests, and a check in with your team. Then anti-nausea medicines, IV fluids, gemcitabine and cisplatin. Any add-on immunotherapy is also given.
Days 2 to 5
Nausea is most likely now, and can show up 2 to 3 days after treatment. Keep taking your anti-nausea medicines and drink plenty of fluids.
Day 8
Blood tests, then gemcitabine through the vein (and cisplatin if your center splits the dose).
Days 9 to 21
Rest and recovery. Blood counts are often lowest in the second week. Energy usually comes back before the next cycle.
