Tumor lysis syndrome can result in several metabolic abnormalities, leading to potential renal failure. If these syndromes are identified promptly, they can be corrected.  

Chemotherapy- and lymphoma-associated metabolic abnormalities:

Question, could elevated calcium be a sign of relapse or disease?

It seems unlikely if it's the only presenting symptom, based on the following:

"Hypercalcemia is uncommonly associated with lymphoma (particularly the b-cell type) but may be seen in centres where many patients with this disease are treated.

Hypercalcemia readily responds to therapy and is a reversible cause of morbidity, but when associated with lymphoma it usually indicates widespread disease. The mechanism of hypercalcemia is unknown but there is strong evidence for humoral factors that may or may not be related to parathyroid hormone."
