What is the purpose of this trial?

This trial explores how paclitaxel, a chemotherapy drug, combined with surgery to remove part or all of the stomach, can improve outcomes for people with stomach cancer. Participants will receive paclitaxel every two weeks for six weeks. Surgery may follow based on the doctor’s advice, with additional paclitaxel treatments possibly afterward. The trial seeks individuals with stomach or gastroesophageal junction cancer who have already completed some chemotherapy, specifically those whose cancer has spread to the lining of the abdomen. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant advancements in cancer treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it mentions that targeted therapy and immunotherapy may be continued, so it's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that paclitaxel is likely to be safe for humans?

Research shows that patients generally tolerate paclitaxel well. In past studies, individuals using paclitaxel for stomach cancer experienced manageable side effects. Most side effects are mild, making the treatment relatively safe.

For instance, one study found that when administered in certain doses, paclitaxel's side effects were not too difficult for patients to handle. While some may feel uncomfortable or have mild reactions, these are usually not serious and can often be managed.

Overall, paclitaxel has been used in other treatments and has a well-known safety record. Doctors understand how it works and what the potential risks are. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Paclitaxel is unique because it targets stomach cancer by interfering with the normal breakdown of microtubules during cell division, which is different from traditional chemotherapy that often targets DNA directly. Researchers are excited about this treatment because it offers a targeted approach that could potentially reduce cancer cell growth with fewer side effects compared to more aggressive treatments like platinum-based chemotherapy and fluoropyrimidines. Additionally, paclitaxel's use in a perioperative setting—before and after surgery—might improve surgical outcomes and overall survival rates by shrinking tumors pre-surgery and eliminating residual cancer cells post-surgery.

What evidence suggests that paclitaxel might be an effective treatment for stomach cancer?

Research has shown that paclitaxel can help treat stomach cancer. One study found that combining paclitaxel with another drug, S-1, extended patients' lives compared to using paclitaxel alone. Another study demonstrated that nab-paclitaxel, a type of paclitaxel, was safe and showed promising results for patients with advanced stomach cancer. While these studies indicate positive outcomes, paclitaxel's effectiveness can vary among individuals. In this trial, participants will receive paclitaxel every 2 weeks for 6 weeks, with the possibility of a gastrectomy based on the doctor's assessment. Overall, paclitaxel shows potential as a treatment option for improving outcomes in stomach cancer patients. ^{1 2 5 6 7}

Paclitaxel (taxol). Kohler, DR., Goldspiel, BR.[2019]

Intraperitoneal (IP) chemotherapy using taxanes like paclitaxel and docetaxel shows promising results for treating peritoneal carcinomatosis (PC) of gastric cancer, with high drug concentrations maintained for 48-72 hours directly targeting metastatic nodules.

Phase II studies indicate that patients receiving IP chemotherapy have a median survival time of 14.4-24.6 months and a 1-year overall survival rate of 67%-78%, but further randomized controlled trials are necessary to confirm these findings.

In a study of 6 patients with gastric cancer, intraperitoneal administration of paclitaxel (TXL) showed that a dosage of 80-90 mg/m2 resulted in significant toxicity, including grade 4 leukopenia in one patient.

Lower dosages of TXL (60 mg/m2) administered intraperitoneally resulted in only mild toxicities, suggesting that lower doses may be safer and warrant further investigation in a larger phase I/II study for patients with malignant peritoneal effusion.
