For curves this follows from the classification of (2-dimensional topological) surfaces, and for simply-connected surfaces this follows from [Freedman's theorem.][1] My former colleagues Anatoly Libgober and John Wood found examples of pairs of 3-folds which are complete intersections and are homotopy equivalent but not diffeomorphic, in fact have distinct Pontryagin classes. See [Example 9.2][2]. Since in this case $H^4(M;\mathbb{Z})\cong \mathbb{Z}$, this implies that the manifolds are not homeomorphic by the [topological invariance of rational Pontryagin classes][3] (see Ben Wieland's comment). For the higher dimensional case see: <cite authors="Fang, Fuquan">_Fang, Fuquan_, [**Topology of complete intersections**](http://dx.doi.org/10.1007/s000140050028), Comment. Math.
