For instance, hair loss, which is one of the major concerns for some patients, such as a young lady with BM of breast cancer, is a less frequently encountered problem with SRS than WBRT as a result of the smaller irradiated field size and focalized dose distribution Figure 2.

All the aforementioned advantages of SRS are provided by utilization of multiple convergent narrow beams to deliver high dose focal irradiation in a single fraction by using multiple cobalt sources, linear accelerators or cyclotrons 37, Similar with neurosurgery, SRS alone or in combination with WBRT has been exhibited to associate with prolonged overall survival, local control and also better neurologic status in these patients compared to WBRT alone 33, However, SRS differs from neurosurgery by offering a chance of ablative treatment to those patients who are rectal cancer rtog appropriate candidates for neurosurgery due to various reasons.

Albeit such an approach may be beneficial in a select group of patients, prerequisites for close monitorization with monthly or bimonthly magnetic resonance imaging MRI and risk for unavoidable repeat SRS procedures for newly emerging BM, both increasing the total cost rectal cancer rtog overall treatment, should be carefully considered Moreover, contrasted with SRS and WBRT combination, the risk for a plausibility of inferior survival outcomes with SRS alone in patients with controlled primary and no extracranial disease should be kept in mind, as it has been accentuated previously by various authors 41, Although local- and distant brain control rates were reported to be better with the addition of WBRT, this distinction did not translate into a notable survival advantage in any study.

Furthermore, in the study by Chang et al.

It is unfortunate to point out that the results of these RCTs ought to be interpreted with caution because of their insufficient design to explicitly concentrate on survival endpoints, such as significant imbalances between the study groups with regards to the prognostic factors rectal cancer rtog utilization of salvage WBRT in SRS alone cohorts 43, First meta-analysis was performed by Duan et al.

In the second meta-analysis, Hasan et al.

Thirdly, the meta-analysis by Soon et al. In the fourth and most recent meta-analysis, by Sahgal et al. Additionally omission of WBRT in this subgroup was not identified to relate with increased rates of distant brain relapses.

In a recent systematic review of rectal cancer rtog studies incorporating BM patients, Gans et al. Therefore, although the concept of TC-SRS is relatively rectal cancer rtog, with its acceptable toxicity rates the results appear to be encouraging for irradiation of a limited rectal cancer rtog with ablative doses of radiotherapy. In a study by Pinkham et al.

Verbal memory and fine motor functions were the commonest parameters to be impaired in this study Theoretically, restriction of the irradiated brain volume with local therapies like surgery and SRS may prove beneficial in preservation of neurocognitive functions without any scarification rectal cancer rtog tumor control rates.

Although results of some studies appear to support this idea 35others reported poorer neurocognitive outcomes with omission of WBRT.

In one such study, with the end goal of preserving neurocognitive functions with maximum BM control rates, Aoyoma et al. Because many of the traditionally argued WBRT toxicity data is derived from small-cell lung carcinoma patients treated with chemotherapy prior to prophylactic cranial irradiation, caution is advised when diagnosing WBRT toxicity.

Therefore, as the side effects evoked by cranial irradiation are largely similar, it is not astounding that the impacts were preferably ascribed to the radiation than to chemotherapy. This information is of foremost significance for radiation oncologists considering the way that almost all toxicities following therapeutic WBRT are almost rectal cancer rtog ascribed to cranial irradiation by the other oncologic disciplines.

Deteriorations in neurocognitive functions may also be already present before the initiation of WBRT. This issue has been addressed in two key studies by Meyers et al.

In the second study by Komaki et al. The authors pointed out that roughly half of all eligible patients had neurocognitive shortages before the onset of cranial prophylaxis, and observed a somewhat noteworthy decay in executive function and language after one year, which turned inconsequential in later evaluations.

These two excellent studies strongly emphasize the paramount importance of implementation of neurocognitive function tests prior to WBRT in order to reflect the actual impact of therapeutic WBRT on neurocognitive domains. Moreover, the negative neurocognitive impact of progressive BM may further be ameliorated or even improved by WBRT in some patients groups with resultant enhancement in executive functions and fine motor co-ordination as neurologic deterioration is reported to directly relate with disease progression in the brain 51, Management of this regretful complication of cancer involves neurosurgery, WBRT, SRS, chemotherapy, and targeted agents individually or as rectal cancer rtog combination of them, regarding the prognostic factors.
