As we only found two small trials with 195 patients altogether, no conclusion for clinical practice is possible. More trials are necessary to assess the benefits and harms of G(M)-CSF compared to antibiotics for infection prevention in cancer patients receiving chemotherapy.
This systematic review compared the effects of chemotherapy alone and chemotherapy plus radiotherapy in adults with early stage HL .For the comparison with same numbers of chemotherapy cycles in both arms, we found moderate- quality evidence that PFS is superior in patients receiving chemotherapy plus radiotherapy than in those receiving chemotherapy alone. The addition of radiotherapy to chemotherapy has probably little or no difference on OS . The sensitivity analysis without the trials with potential other high risk of bias showed that chemotherapy plus radiotherapy improves OS compared to chemotherapy alone.For the comparison with different numbers of chemotherapy cycles between the arms there are no implications for OS and PFS possible, because of the low quality of evidence of the results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
